Oh, I am sorry. I hate AF! She is such a b*tch!
most people dont test until 14dpo. give it two more days.
If you are only 10 dpo, you might be still too early to trust a pregnancy test. Sore breasts are a sign of pregnancy AND a sign of your period coming, so it is a hard one! Very good luck to you! We are the same age and in the same position, so I understand what you are going through. I hope to start clomid soon.
