hello Dr. Rynne,
I really need your opinion. first of all I have no idea why they calculate your pregnancy from the last period(the 1st day of last one) while it should be calculated from 13 days after the intercourse. right or wrong? Anyways my first day of my last period was 18 or 19 Dec or 20 not sure exactly. on the jan 22 I did a pregnancy test by my dr. she said I am pregnant. so she sent me to the first ultrasound on the Feb.13. the lady didn't see anything by external ultra, so she did an internal scan. she said the size doesn't even tell me this is even 6 weeks. I checked with my Dr today she said we are either wrong on the timing or the embryo is not growing. So what do you think?
