So I’m on birth control and I take it regularly and I had sex for the first time in a while and use protection which I had done is over about a year bc I was in a serious relationship that night I had started to spot blood and it stopped a few days later I’ve started to have brownish pinkish spotting and it’s been happening for probs about a week... does anyone know what this means?

(These obviously don’t have the pink spotting but I did for about a day)
