Is my period coming?

So Sunday, about two days ago, I noticed some brown blood (a very small amount) on the toilet paper when I wiped and I was literally about to have sex with my boyfriend lol so I put my finger in to check there wasn’t a bunch waiting to come out and wiped that on the toilet paper and saw the same thing so I was like nbd and we had sex anyways. I’m on birth control so he came in me and now my period hasn’t come. So I’m confused as to if that was my period or if I’m still waiting for it 🤷🏻‍♀️
