Hi, Recently I had sex (with condom) and it's always been with a condom but I think a day or two later I started to bleed really dark brown blood and I didn't think much of it cause it was so small but then it started to come out more but enough to wear a pad (I started to use a pantie liner but it wasn't enough and this isn't my normal monthly bleeding) and just a day ago it started to turn red like normal period red but still not like my period should I be worried? My period was a month ago today but I still don't see any reason for me to be pregnant.
