My wife is 11 weeks pregnant. with twins, she has done well, and all the levels were extremely high, she has had brownish spotting, we went back every week, and did Ultra sound, everything was fine, just take it easy and rest. Today, she woke up, and had some bright red bleeding, it stopped pretty quick, two hours later, she had just a little bleeding and a small clot, the size of a small pecan. we have seen the babies, and they were both doing well, the previous week. We are very concerned, our next appt for an ultra sound is next weds. anyone experience this, your help is greatly appreciated. thank you.
