Hi Gaals ❤ i used to get my cycle every 6th of the month and but in may 2016 i notice that my cycle has changed. My cycle now comes on the 23rd or 25th of every month , me & my boyfriend had sex july 3rd and i was fertile. June 22 i took a preganancy test and it was negative. My right boob is kinda sore and i been getting slight cramps in my stomach and today i got this brownish discharge ? What should i do girls?
