Just going to label this as possible TMI.

I'm four days late on my period, and the month ends tomorrow 😕 I'm also suffering from strep and I'm taking penicillin antibiotics for it as of 2 days ago. I've also taken 2 pregnancy tests that have been BFN. This morning when I checked there was some white discharge, but my vagina seemed a little red and sore? I've only had one sexual partner these past 8 months and that's been my husband and he has also only been with me these past 8 months so I've ruled out an STD. I'm a little confused and need some advice from you guys about what I should do! I can't afford to go to see a doctor right now.
