So my husband and I went in yesterday for our 7 w 3 d appt and during ultrasound dr couldn't find heartbeat.. She we so nonchalant about it like I think the baby stopped growing at 6 w 6 days and I'm sorry but I can't find a heartbeat I'm gonna have u guys come back later today to get a better ultrasound done downstairs with a tech on a better machine to clarify there is no heartbeat?!?! We were absolutely devistated I cried for four hours waiting to come back in for second ultrasound at 1:00...thinking we had lost the baby.. We came back in at 1:00 and tech was asking all kinds of questions.. Any discharge, cramping, sharp pains.. I've had nothing.. So she  started ultrasound and immediately we saw the flicker!!!! My husband and I were both in tears!! Of joy!! Hb is 159.
