Happened at my first appointment by my LMP I was supposed to be 8wks but the ultrasound showed 11wks. Ultrasounds are way more accurate than estimating by LMP.
My 3rd baby this happened to me!
I may sound crazy bt no doubt I think am supposed to deliver sept 3rd but my babys measurments sebt me bak to sept 16 hopefully wen I go on the 29th I go bak to what I suspested. ANYTHING TO SEE MY BABY SOONER
Happened to me - I thought I had my "period" the first month I was pregnant. Didn't find out I was pregnant until I missed the period after that. We thought I had only just conceived until my sonogram and then all of a sudden I was two and a half months pregnant...
Perhaps what you thought was your last period was actually just implantation bleeding...
Wow that's crazy! Maybe u were pregnant while u had ur "period". It was prolly heavy spotting or something. Its rare, but it does happen.
that a estimated due date. once yuh go for your actually sonogram they will tell you because they got by the measure and the baby
