What Causes Dark Brown Vaginal Bleeding Despite Taking Plan-B After Having Unsafe Sex?
My bf and I had unprotected intercourse and I took plan B 2 days later but a week after that I started what I think is my period, although it is very light and a dark brown color I am not on birth control but I have taken plan B and I m very nervous not sure what it would be I ve never had this happen before. Thanks

Hello,
Plan B is a high dose of progestin and so it can throw off the period and make it irregular both in timing and flow. Dark brown blood just means that there was less flow and so it sits in the vagina longer and gets oxidized from red to brown.
Hope I have answered your query. Let me know if I can assist you further.
