Accidentally didn’t pull out all the way 😭😭

I just quit breastfeeding less than 2 months ago, I’ve only had 1 period since. Tonight we had an accident and he didn’t pull out all the way… most of it didn’t get in me but a little did, I took plan b like 15 min after cause when I checked my app it of course says today is my ovulation day… but it’s my first cycle since before I was pregnant and my daughter is 9 months so.. idk how accurate my ovulation day would be, anyways, I’m freaking out… some one tell me I’m okay pls 👀😭
