BC Advice

So I have an appointment with my Gyno this week to get on birth control. I'm 19 and I have heavy periods due to Endometriosis. I've never been officially diagnosed, but every female on my mom's side had/has it. My doctor said I most likely have it and he ruled out other reproductive diseases like PCOS, etc. when I was 17 I went on the pill. it worked great for my heavy periods, but I got some pain in my legs and that's a big no no because it's a sign of a potential pulmonary embolism, so he took me off of it.

I'm in a new relationship and my boyfriend and I haven't been using any birth control. He pulls out but I'm too paranoid. So I want to go on BC again. I know BC effects everyone differently but I've heard horror stories about people who have gone on BC and they bleed for months at a time and gain a ton of weight. I just came off of an antidepressant that made me gain over 80lbs and I'm starting to lose that weight.

What are some BC that you ladies have tried that didn't make you bleed constantly. I'm fine with taking a pill every day. But I need more details about some different types before I go to that appointment.

Thanks in advance.
