ok so my period usually lasts for 7 days . i just got off of my period saturday then when i went to the bathroom monday i saw that i was spotting. i have no idea whats going on. there is no smell to it or anything. i don't know whats going on and i'm starting to get worried. my bf and i have been ttc for about 3 months . we had sex the day we ovulated then two days later i came on my period so could i still be preggo? what else could be wrong with me? please help.
