To the woman who had bleeding resembling a period towards the end of her first trimester (I apologize for not having your name handy): I need to double check my sources, but to the best of my knowledge, it is possible that your bleeding was caused by a rocky transition of hormonal production from the ovaries to the placenta. If anyone else has information on this, I would be interested to know about it. Anne McDermott In CT, where we're anxious to get the wood stove fixed.
