sex a week before period and a week after app ovulation estimate

Husband and I just recently tried for a baby. We had sex twice in a row about a week after my app says I've ovulated. My period will be here in a week. App says there's a 3% chance. I know it's too soon to tell but has anyone else had unprotected/unpulled out sex a week before period and have gotten pregnant? I'm curious to know. Even if I'm not or it's not possible we will probably keep trying. I know I'll need to wait a few weeks to test or if my period comes it's a no. Lol
