Pull out method

Annie
according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> I'm ovulating but my boyfriend & I still had sex using the pull out method. he usually does it correctly & finishes on my stomach after jerking off a bit on me but this time he came immediately after pulling out. he said everything's fine but after asking a lot he said worst case scenario, he could've ejacualted very little when he was pulling out. he said he wasn't like ejacualting as he pulled out but idk what to think. also i've take plan b twice this year and it's messed up my cycle a lot so i really don't want to take it unless it's an emergency. we've used withdrawal so many times so idk if i should be freaking out
