So I’m going to try to make this short an sweet. But I’m going to start from the very beginning. Due to weight problems I will miss my period until I become healthier. So from November to March 9th I didn’t get my period. From March 9th through March 13th I had my period. ( began becoming health again) Began with the old blood and become like a regular period. So last Saturday I had unprotected sex and he came in me. Last Sunday morning I took plan B. My calendar says I began ovulating on Saturday. Today I noticed I had cramps and slight back pain. I then went to the bathroom and saw blood on my underwear and when I wiped. It’s medium to light blood, dark/ becoming lighter. The pain is horrible. I feel like my vagina wants to just pop out of me. I never bleed during ovulation. Could the bleeding be from the plan b? Should I be concerned? Anyone else have this experience?
