hey guys. so i have had my second depo shot already. so i've been on it for 5 months. so i have another month still on it. about a week ago i had intercourse with my boyfriend. two days ago i noticed spotting. it was very brown at first, and throughout the day is got very light and turned pink. yesterday i had no spotting at all. so i spotted just the day before yesterday. today i went to use the bathroom, wiped and there was just a bit more of that pink spotting. not on my underwear but when i wiped. i havent felt any bad cramps but i've been feeling very uncomfortable. can anyone help amd tell me whats going on?
