Same thing happened to me. Turns out I ovulated late, then my egg took a few days to split in two. 15+2 with twins. Good luck.
I went through the same thing. 22 weeks, and doing great! Its just too early.
At 5 weeks all they will see is the yoke sack and possibly the fetal pole. Even seeing a heart beat is difficult at five weeks. I am a midwife. We NEVER expect to see much at 5 weeks on the ultrasound. So much is dependent on the placement of the fetus. If we do an ultrasound sound this early we are checking yoke sack placement . Looking for atopic pregnancy not much else. You blood work is a better indicator of fetal growth so don't panic and get a new dr.
I think it's a bit insensitive for them.to act like that. If when you go back all is well, might consider a different doc. You'll be spending lots of time with them and if their bedside manner ***** then ditch them!
If you're 5 weeks, it's perfectly normal. My periods are also irregular and with my current pregnancy I should've been 3 weeks ahead based off of my LMP. I knew that there was no way in he** that i was 9 weeks at my first ultrasound. Try not to worry.
I hope all goes well with your pregnancy when I found out I was pregnant based on my menstral cycle I should have been 5 weeks but went to the ER and ended up only at 3 weeks so we only got to see a sac now I'm 38 weeks today.
I don't know why she so called with you but if she saying your only 5 weeks its still to early...
