Missed three BCPs, unprotected sex!

My husband and I went on a trip, and I forgot to pack my BCPs. We also had unprotected sex on the trip multiple times while I wasn’t taking my BCPs. This isn’t such a huge deal - we have a 14 month old and have been talking about me going off BCPs in a couple months to start trying for number 2. Otherwise, I would’ve made him wear a condom. I began to have moderate breakthrough bleeding between days 2 and 3 of my trip. I started a new pack when we got home, and the bleeding stopped within six hours of taking my first pill.

My question is - if I had breakthrough bleeding (moderately heavy) on day 2-3 of skipping my pill, does that mean my likelihood of getting pregnant after this past weekend trip is pretty low? I was halfway through my pill pack.

Again, I know skipping birth control/having unprotected sex = not a great idea, but since we’d agreed we’re gonna start trying soon anyway, neither my husband nor I thought it’d be a big issue. I’m just wondering what my chances are of actually getting pregnant from this weekend.

Thanks ladies!
