8 DPO...already worrying that I’m out

Annie

I’m 8 DPO I think, but I don’t know if it’s possible this month. I’m not using OPKs, but I did have lots of eggwhite CM from September 12-17. BDed on the 13th and the 16th, and had cramping and tender breasts on the 18th, which makes me think that’s when I ovulated. Am I out? Did I BD too far ahead of O time? My husband was out of town for work so we weren’t able to do it more often. Anyone have any experience with getting pregnant and not BDing on the O day?
