Bleeding with Ovulation?

I'm 3 months PP & my hubby & i aren't rushing for baby 2 just yet (but we wouldn't be upset if the day comes sooner rather than later) I did get some BC pills from my OB (original plan is to stay on them until my son is 1) and my doctor told me to just start them right away. But for some reason i have a gut feeling I'm gonna get pregnant this cycle. My hubby & I DTD 2 days in a row and he came inside me both days.. Then 2 days later i have ovulation cramps / fertile CM & then we had sex that day also and he came inside me also.. Meanwhile ive only been on BC maybe 3days before that & then following day I had some bright red bleeding that stopped a few hours later.. Not a consistent flow.. But I never have bled before around ovulation.. So I'm not sure what is going on with my body. Either way I wont be disappointed period or baby lol but I'm more so hoping for baby 2 to be on his or her way ! Anyone bleed around o day?
