[|Human|] Sabitha Fazal: My last period was June 6th, and came to know the pregnancy on 11th July of Positive. Would like to know that what would be the baby s week? Moreover, I was effected with Chicken Pox on the same day. is there any adverse effect to the baby s growth or should I think of any alternative? Please advice Thanks & Regards
[|AI|]  Hi there,The pregnancy is always counted in weeks from the day of first day of the last menstrual period, even if the baby was actually formed after ovulation that usually occurs 14 days after the first day of the period. This is to make it easier to date the pregnancy. So the only date you need to remember is the first date of the last period. Chicken pox this early in pregnancy should have no effect on the baby. It is more of a concern if chicken pox is acquired after the 12th week when it may cause deafness, cataracts. And if acquired after 28 weeks almost 10% of the mothers develop chicken pneumonia which can lead to hospitalization and can adversely affect the pregnancy. So you need not worry if you have had and recovered from chicken pox, because once you get the virus, your body develops immunity to it. Hope this helps. Regards.
