Went to the doctors to tell them that I was pregnant and have come away feeling down. I'm confused about how he worked out my dates and he also spouted a lot of statistics about how likely I was to miscarry. I know I should be realistic but this has just made me feel like I should reign all my excitement in. Basically, I had sex on the 1st of the month. Had a negative blood test on the 12th. Did not have sex again until the 15th and didn't take an HPT until the 22nd which was positive (who knows when I could have got a positive if I'd tested after the blood test). He's saying that on the 12th I wasn't pregnant because the HCG was negative. I get why he says that but if I had sex on the first and wasn't pregnant on the 12th then where has this positive come from? He said that the sperm could have stayed alive for a few days before I ovulated and then it takes several days for the HCG to be present so I wasn't pregnant on the 12th. Urgh. Anyway, he's saying I'm maybe about 4 weeks - or 1 week if we take the 15th as day of conception which seems unlikely to me with a positive HPT 7 days later - and to go back in 4 weeks to see how I'm going. Unless, of course, I'm miscarrying in which case I should give them a bell.
