ovulation confusion.

Sophia

hey everyone. so according to when my app says i ovulated, i had sex 2 days after that. then 2 days after the sex i was having cramping all day (yesterday). i know thats too early to be implantation cramping, and period due in a week. i dont actually know when i ovulate so does anyone think theres a chance i conceived? or anyone who has conceived on cd19 of a 27-28 day cycle?
