On ALL OF MY FIRST 5 PREGNANCIES, I was at least 6 weeks. But this last one now..... I was right at 5 or 4 weeks and 5 days. Reasons I found out earlier was, we were trying for almost a year to conceive. I checked all the time hoping for a positive. Finally I got a positive after many disappointing negatives. My husband said go get tested at dr. So they drew blood and I was almost 5 weeks. My hug level was around 1200. So he thought I was further along than I really was. But then I did another test and it was over 2000. High enough for ultrasound. Reason my hug level was so high and I thought we conceived earlier than we actually did...... we were pregnant with TWINS!!! Sad that only one survived past 9 weeks, but we are 21 weeks with a healthy boy!!
