Chickenpox can recur but that is rather rare. Immunity is usually life-long. This
means, contact with a person with chicken pox when you are pregnant should be no
cause for worry if you had had it yourself in the past.
Lactoferrin supplement useful in pregnancy? It is somehow doubtful
Conception with an under-active thyroid
Question: My fiance has an under-active Thyroid and is worried after marriage, that
if we decide to have a child, this will affect the development and birth of the child.
I have not been able to get very much information on the internet other than miscarriages
and things such as that have been associated with it. Is there a list of things that
have been diagnosed and what can a couple do with there doctor to keep this regulated
if it is indeed a big deal. S.W. (USA)
Answer: An underactive thyroid is associated with potential fertility problem including
erratic ovulation (which can make it difficult to conceive), increased risk of miscarriage
and prolonged pregnancy. The use of Thyroxine replacement for such a woman is strongly
encouraged. Using Thyroxine during pregnancy is essentially safe. However, a Swedish
study covering a period of 10 years, up until 2004 showed that women taking thyroxine
during pregnancy have a slightly higher risk of such complications as pre-eclampsia,
gestational diabetes and the need for caesarean section. Babies also showed a very
slight increase of congenital anomalies. However, absolute figures of these were
quite small. A summary of this study published in June 2008.
All in all, a woman with an under-active thyroid will be strongly encouraged to use
Thyroxine to maximize her chances of successful conception and minimize risk of complications
associated with the condition.
Slight bleeding and positive pregnancy test
Question: My period appeared to arrive 1 day late this cycle, but only a slight pinkish
discharge which hasn't developed into a proper bleed... I am booked for a fibroid
removal by hysteroscopy operation in 2 days time so i have just done a pregnancy
test which says that i am pregnant. Is this possible? I know bleeding in early pregnancy
is fairly common, but is it usual to begin bleeding when menstruation would be due
and to be pregnant? I am a bit confused! Obviously i'm going to cancel the operation
in case i actually am pregnant. Thanks for reading this. H.M. (UK)
Answer: It is entirely possible that you are pregnant. In any case, with a positive
pregnancy test, your hysteroscopic myomectomy is going to be cancelled.
Slight bleeding in early pregnancy roughly coinciding with the time when the period
was due is not uncommon. it is generally believed to be an implantation bleed'. This
might be what you have experienced. There is, of-course, that small possibility that
yours was a false-positive pregnancy test. The rate of false positive tests is roughly
around 2% or 1 in 50. A repeat should remove that doubt.
Exposure to chicken-pox in early pregnancy
Question: I am currently about six weeks pregnant, I just found out that my best
friends son who I watch on a regular basis may have chicken pox or measles. I have
had shots for measles and have gotten chicken pox twice, is there any concern for
my baby? K.D. (USA)
Answer: I think you can relax. Since you have been immunized against measles and
you have had chicken-pox, you are almost certainly immune to both. This means, whichever
infection this child has, it will not affect you. Immunity to both tends to be life-long;
a fact which brings me to the second issue. You mention that you have had chicken-pox
twice. This is, in theory, possible but in practise, it is very rare. It is therefore
possible that one of the episodes you had was erroneously labelled as chicken-pox.
In any case, that is academic now. The important point is that you are not at risk.
Lactoferrin supplement in pregnancy
Question: Is a lactoferrin supplement safe to take during pregnancy? The supplement
is called 'face to face' and is available in Superdrug. It is to help clear your
skin as I'm really suffering with breakouts, I'm 13 weeks pregnant. I contacted the
company who said its safe but I found some contradicting advice on the Internet about
lactoferrin so just want a second opinion. Thanks. C.K. (UK)
Answer: Lactoferrin is a natural protein. There is plenty of this in milk and in
fact human milk has ten times higher concentrations of lactoferrin than cow's milk.
It is known to have strong and broad antibacterial and antiviral activities and this
is one reason (among many) why breast-feeding is so encouraged.
Lactoferrin's progressively increasing levels in the body during pregnancy and its
abundance in normal food mean supplements of this are almost certainly safe in pregnancy.
It has even been used as a supplement substitute for pregnant women who cannot take
What I'm rather puzzled about is its claimed benefit with skin breakouts especially
during pregnancy. When these occur, it is almost always a hormonal effect. Yes, lactoferrin
has anti-inflammatory properties but this is hardly relevant here. I cannot therefore see by
what mechanism lactoferrin can help with such breakouts.. However, if your experience
is different, I cannot argue with that.
