Hi...so me and my boyfriend are not trying to conceive but we have had sex without a condom. About 4 days ago I had brown discharge when I wiped and then it stopped the next day...at this time I was about a week and a half away from when my period was due. Now I am having twangs or sort of aches in my left hip area...I just wonder if this is suspicious or am I worrying about nothing?? Thanks guys!!!
