To all that replied... Thank you for your opinions they are very helpful.
When I had my Dr appt. on 5-5 they mentioned an u/s but the other nurse that came in to find the heartbeat said something about the heartbeat and they set another appt. for 5-17 and I was told that was odd because I shouldn't have another one for a month, so my nurse practioner might have something to say about it, the heartrate was 170 on 5-5, they only found one so I dont think there is more than one but it is very possible for there to be multiples because it is my generation for twins on my dads side, my mother had twin boys 7 years ago but she was 35 when she got preg. so it could have been her age since the older you are the better chance you have of having twins or several babies. I would feel alot better if I had a u/s done because then I would know for sure, I will see what they ssay at my 5-17 appt. and if she says the same as the others then I will ask for a u/s.
