Okay I had an ultrasound yesterday and she said my uterine lining was thin, I had a cervical examination last week and have been bleeding ever since. I thought for you to have a period your uterine lining got thicker then sheds. So am I right in assuming I am bleeding from the examination not I'm having a period? I'm on the depo shot and I haven't had a period for 7 months. Sorry if this sounds dumb I'm just trying to fix whatever problem is happening. P.s I am having all these examinations for unexplained extreme bleeding during sex, it's been happening for 5 months.
