hi all, i am sure you are all mega busy but i need to know at what stage your twins were detected in pregnancy. i am on my fourth pregnancy in 4 years 2 beautiful healthy boys and sadly my 3rd boy died at 6 weeks from sids in march. i am currently around 24 weeks pregnant and have had 3 scans, first scan littrally 2 minutes - theres baby theres heart beat, my second scan hazy but at 18 weeks i was told girl, ( having done this so many times over the 4 years i was conviced its a girl also - definately no spout to speak of) scan lasted about 3 minutes. 3rd scan 22 weeks, lasted about 5 minutes, checking heart measurement, then at the lasty minute the lady said do you know how i said girl, this baby has turned into a boy!! confuzed much!!! any way these things happen, still excited but then i was given a doppler to ease my stress with all that happened previously and every day for 18 days i get 2 heart rates one is constant 130-136 (sounds like a train) then i get a 169-177 about an inch away. do you think i could be having twins and one is just hidding behind the other or do you think its just coincidence?
