I have a strange situation for you. AF came April 4, and then again April 26. Thought I was PG when nothing happened May 20-26 becuase I am extremely regular, and I moniter like crazy. I kept taking HPT, and they were negative everytime. I figured it was too early. Then I took a cheapo HPT- Answer brand, and two came up (+). Super exciting! The next day, (Thursday) I went to my OB to confirm PG, and she told me that the levels of hCG were extremely low- although present. Plus I was bleeding, so that was a bit of a concern. They sent me for a first Trimester Bleed scan, where the radiologist told me that I was not pregnant. He couldn't see anything. Not even a sack. The OB called on Friday ordering Blood work- so I went for that, and it was once again (+) for PG hormone. The DR.s think I may only be 4-7 DAYS pregnant. How weird is that? Normally when you find out your pregnant you already have a month taken care of. Anyway so I am working a midnight tonight- I'll get off at 7, I have to go back up to the Hospital for a second blood test to make sure hCG levels are increasing, and if they have increased, I am PG!! If not, I miscarried at the end of April when I had AF visit 2 times in a month. Does anyone have ANY advise, or have you ever heard of finding out you were pregnant 2-4 days after intial conception??
