Help! Problem Pregnancy

I have had 3 premature babies one 3months early (I had a complete placenta preivea with this one) one 2 1/2 month early and the other was 2months early and he tryed to come 4month early. I also had one I thought I was going to miss carry in the first trymester but didn't. they are now 28,24,23 &21

i recently found out that i am 9 weeks pregnent and not 11 like we thought. In our check up though the doc could not find the heartbeat with the machine or with an ultrasound should i be worried yet or keep patient?

A relative of mine gave birth on Thursday and she's had a lot of trouble. I am looking for someone who may have had a similar situation and can offer her some personal words of encouragement to get through this.

The situation is nearly identical to the story Melissa posted here, only my relatives
