Bleeding help!!

So ive I just started having sex 6 months ago and everytime I have, I bleed but not a crazy amount. I’ve gotten multiple test done and examinations and doctors said I have a tilted uterus and a sensitive cervix which can cause bleeding during and after sex. They said the more I do it and when time passes, it will go away. There’s been times where I don’t bleed at all during sex. I bleed about 75% of the time. I’ve gotten on the pill birth control recently and it’s week 3 for me. Since I’ve been on it, I’ve only had sex twice and it was an abnormal tremendous amounts of blood pouring out of me within 5 mins of intercourse and I would still spot the next morning. This has never happened before this much and this fast. I scheduled another gyno appointment to figure if it’s the birth control but while I am waiting, I was wondering if anyone knows what it could be? The pill? Or the combo with my tilted uterus? Does the pill make the cervix more sensitive? Thanks!
