Okay so me and my boyfriend have only had sex 5 times and used a condom every time and he has never came inside me or even near my vagina. And the past 5 times have been between August 24-October 1 (idk the exact date of each time but that's the first and last time we did it so the other 3 times are between those dates). I haven't been experiencing any pregnancy symptoms besides a little light headed/headache and I just noticed a little bit of light brown discharge but not enough for it to be my period. Also my period is supposed to start in 8 days. Should I be worried?  Could I be pregnant? Or is it just pre period symptoms? Please help!
