Had sex for the first time. I kept bleeding after which was expected but…

So Wednesday of this week, I had sex for the first time and of course bleed and all that jazz. Now I’m at Friday and I’m almost like discharging brownish red stuff that I’m used to seeing at the beginning and end of my cycle. I had my period the week prior before having sex. I was not taking my birth control correctly last month. I don’t know if that’s relevant. We used a condom as well. I’m just giving the facts in case someone knows what’s happening. Is this normal? I know it’s normal to bleed, but this discharge that’s coming out is something I associate with my cycle. I’m confused. Can I have sex again while I’m like this or is it gross because I find it gross.
