My period is 30 days late now. I took plan b 30 days ago (the day my period was supposed to start it didn’t so I had sex, condom broke) I’ve had zero positive pregnancy tests and yesterday a new period was supposed to start, it didn’t. Today I’ve had cramps and earlier when I wiped I had pink and brown discharge so I thought my period was finally starting. I used a tampon because I had to drive for over an hour and didn’t have any liners/pads. Well I just got home and there was pink and brown on the tampon again. Now I’m worried plan b didn’t work and it’s implantation bleeding 🙃 should I test again? Last test was last week.
