I've been experiencing bleeding just during sex (no pain) for the past few years and I need an explanation. It all started when I switched from Orthotricyclen to Ortho Lo. That whole year I would always bleed during sex the week before my period. My doctor switched me to Yasmin and it happened again the 2nd month I was on it. So now I'm back to regular Orthotricyclen (generic, Trinessa) and I'm honestly just too scared to even have sex so I don't know if it is still happening. I'm so scared I have some type of cancer, endometrial, uterine... My last two paps have been normal. Is what I'm experiencing just due to birth control? Please help.
