Last time I all of a sudden thought something was wrong b/c the soreness in my boobs went away. I took another test and the line was getting fainter. So I called for a blood test. I think that was 17DPO and it came back at 36. Then 19DPO it came back at 22. So at 15DPO and 148, I'm already higher than what I was 17DPO last time, but I think my numbers had already fallen by the time I got the blood test last time. Your numbers look in the higher end of normal which is fantastic! I never got a positive ovulation test this past month, so I'm not positive when I ovulated, but guessed it to be Monday, Feb. 19 based on cervical mucus. We BD on Saturday, Feb. 17. It was a busy stressful month and that was the only time we BD that entire month! I'm thinking I could have not ovulated until Feb. 20, which would make my hcg numbers even better, but I really can't determine because I didn't devote the normal effort to tracking my cycle this past month. Dang! I can't even remember for sure when I started my period, but know it was around Feb. 6-8!
