Question: i had sex on the 26th of april, about 3 or 4 days after i finished my period. (unprotected sex but i'm on BC) then about 10 or 11 days after that, i started spotting. it lasted for three days then stopped. then last night, about a day after it stopped it came back. its not a lot and it's mostly brown now. last night it was red but today it's been brown and im getting cramps. i'm having a hard time trying to figure out my odds of am i pregnant or is this just my cycle changing? i know that no one can tell me if it's one or the other but as anyone else experienced this? what did it end up as, pregnancy or period changing???  ?
