[blahblah8]

I am 13 wks n 3dys today. My last period was sept 28. I bleed for 5 days. I had pretty regular sex with my bf the first 2 weeks of oct. I jad sex one timeon oct 15 and it was unprotected. My due date is july 4 th, with everu pregnancy calculator ive used , the dates of conception say its my bfs baby. The ultra sound measurements also give the correct lengths that iys my bfs because of yhe number of weeks i measured. I am jus scared because it cld be the other guys by a weeks differance. Should i b worroed???

I can't say for sure, early ultrasounds are more accurate than later ultrasounds, but they can be off a few days to a week. Conception dates can be off too. So again, with a week's difference in the same cycle, you'd want a DNA test.

8 weeks! N before that i had my hcg taken and it put me at 4 weeks which still lines up. Is 8 weeks early enough to b accurate???

How far along were you when you had the ultrasound? If it was done really early, you might be able to be more confident, but a week difference within the same cycle really isn't enough time to tell for sure.
