I’ve been on Cryselle birth control since june this year and my period has been regular. I’ve had sex for the first time on the 15th Of sept with a condom. My period was suppose to be for 5 days (started tueday but was only 3) meaning nothing was there on the last two days so i didnt pay it no mind. I did bleed for one day after that but on friday i noticed brown blood when i wipe and it continued until today. I was kind of sick that week and took my pill at my normal time and drunk medicine 5 hours later. Would this be implantation bleeding? Ive taken two test that came back neg and today my AF is due but im still seeing brownish/a bit red blood that is extremely light.
