pregnancy or BC symptoms?

This is going to be a little confusing but here it is ! ... so I recently stopped my birth control on April 20th after having my period on April 11th. I then had sex on the 23rd and withdrawal bled from the 24th to the 26th. Since then I've had sex on May 1st and 6th. I had some clear discharge for a couple days the beginning of May but it went back to normal. I know after birth control getting pregnant can be tricky but I've had constant headaches and Recently I've been so bloated that I always feel full and I've been having mild cramps and now recently really low I've been having pelvic tingly/pains. I didn't have any symptoms from my first pregnancy but could I be pregnant already ? Even tho I was on BC I was supposed to ovulate the week of the 24th and my calendar says I should have ovulated May 3rd to May 8th. But then again BC could have messed that up.
