My period ended on 9/19 but I forgot to take 3 birth control pills from 9/22 to 9/24. I had sex on 9/23. When I realized I missed the pills on Monday 9/25 I immediately took them. On Tuesday I began to feel sick and I began to have brown discharge which lasted for about a week. The discharge then turned red and has continued up until today. My period is supposed to come on again today but instead the bleeding has recently tuned to a light pink. I’m not sure what happening.
