Ovulation and symptoms

Danielle

Hi this last test is from tonight at 20.00 the 4 before that are from yesterday. Am I ovulating tonight or did I ovulate yesterday or both days? Also Iv been having this strange pain in my stomach all day today not quite cramps but definitely a pain.. hard to describe. Also I have a sharp shooting pain in my bottom when I sit down!! Are these signed of ovulation? Also if I have conceived this month what type of symptoms should I expect within the next few days and how soon can I test? Thank you x
