Dpo?? Tmi.

Thursday I ovulated. 1 dpo I had pains in my ovarys and sharp pains in my uterus. 2 dpo constipation that started at 1 dpo at night and continues til now. Emotional, a funny, fuzzy feeling on my right side lower than my belly button. & Neasus. We had sexual intercourse 3 days before ovulation. Is it possible to get pregnant having sex 3 days before? And symptoms so soon? Anyone else have this? We are ttc with baby #1. Please help ?
