Hi I had my period on June.26 the first 3days were very light, over the last 2 it was getting heavier. But this month I had an extra day in my period so instead of 5 days It was 6. But on the last day it was brown blood coming out. My period ended on July.2, now on July.8th I am bleeding again, the blood is brown. Yes i am sexually active, I did have sex 2 days ago causing my vagina lips to swell up. I almost had sex June.9th and June.23 . I just wanted to know is this a sign of pregnancy, is something wrong with me or is this normal ?
