ok i had a bfp so i set up a dr appt. i had a few negative test results but now they have all been positive. i had a ultrasound yesterday and there was a gestational sac but you could see the inside thickeneing(they said this was a good sign). they got a BFP from my urine and i had my blood drawn and im suppose to go back tomorrow to have my blood drawn again because they say that HCG levels double every 48 hrs. I'm just really nervous that something is wrong like a tubal pregnancy or miscarriage..have any you had this happen? i found out that i was preggo with my first and 4 1/2 weeks so i guess its possible i find out fast.im upset that i couldn't get a confirmed pregnancy via ultrasound.
