I had what I think is my period on tuesday and it ended Wednesday night into Thursday morning. it was super light ot didn't even mark up a pad but when I used tampons it was more prevalent. On the Sunday I started my placebo week I had a single concentration of blood that was bright red then went away until tuesday. I am on the pill. also this Thursday I had got strep and day 3 into treatment I have cramping and found a teeny tiny bit of blood like almost unnoticeable. could that just be left of blood? I'm really stressing out. I am on amoxicillin and cadista which is a steroid for pain. and i didnt get strep till after my period and i was taking vitamin c to help it along. please any help to ease my mind. I thought all this stress was over.
