Help I need advice or reassurance!

I’m hoping someone might have a similar story, idk I just am freaking myself out right now. My 2 month old baby is EBF, I’m pretty sure I have had my period twice, the last one was a couple weeks ago, and I had been having a bunch of cervical mucus, so I sensed I was ovulating. But here’s the stupid part my dumbass forgot two days of my birth control because I was busy when my alarm went off for it and forgot about. And of course we had sex on both of those days. I realized I forgot to take them the other day and am now back on track but I am terrified to get pregnant this early again, I was not planning on having kids for another couple of years.
