Missed pill

Tia

I’ve been on the pill for over a month now and I missed two this week and was having sex through out it as well. I started having some brown discharge every time I wiped and now it’s came to full on bright blood. I have very faint lower belly pains that come every now and then but they don’t feel like my normal period pains. I had a period about two or so weeks ago which messed around a bit because of the pill so could this just be a period coming early? Sounds silly but I had some of the same symptoms when I was pregnant with my little boy and would just like some opinions.
