it maybe just to early to see, they should have done a vaginal u/s and that would have given a more clearer picture of where your at, although if your less than 4 weeks nothing would have shown even with that, try not to get too worried, you prob should have a couple of blood tests done to check how your hcg levels are rising, if they are doubling every 48/72 hrs then at this point there is nothing to worry about, they need to rise by a minimum of 60% early in pregnancy for it to be viable, you should also have another scan in around 1-2 weeks time and this should show a big difference, good luck
Oh sorry my last period was October 15th.
No. I haven't been scheduled for a repeat ultrasound. The tech said my ob would contact me in the next day or so. It just feels like forever and I'm really good at working myself up about stuff. Thanks.
My opinion is that the only way to know for sure is to do a repeat u/s. Sinced you said that you have irregular cycles, there's no way to know how far along you should be. When was your last period? It may just be too early to see anything besides the sac if you're only 4-5 weeks along. Have you been scheduled for a repeat?
