unsure

hey guys, for the past week and a half I’ve been having a lot of pain in my lower belly. stabbing in my ovaries, and cramps pretty much constantly. my lower back has been very sore as well and both of these are to the point of where I need to lay down and I haven’t been able to work and play sport etc. I feel nauseous and dizzy constantly but not to the point of me actually throwing up. I have tried taking Panadol, nurofen and period medication like naprogesic and ponstan but heatpacks are only the really thing that seems to help. I don’t get a lot of pain during sex but I do get some when it’s deep and a lot when it’s first started (sorry for TMI) i find that I also bleed very irregularly even though I am on the pill, where I will wake up and bleed everywhere then I’ll stop by the afternoon and then i will sting when peeing and stuff, then it might happen a few days later, and I also tend to have very very heavy periods and once I am on them I get deep pain all down my legs, cramps, very tired, headaches etc. I have seen a doctor and we have ruled out cysts on my ovaries, uti’s, pregnancy, appendicitis, std’s through urine tests and ultrasounds. I am booked in to get blood tests tomorrow, and he says that if I get more pain when my period starts then it may be possible that I have endo but we will have appointments with a gyno and obviously then consider the surgery. was just curious to see what you girls thought about this? also thankyou so much in advance for your help and I hope that this doesn’t offend anyone and I know you’re not doctors but I’m just genuinely curious what people who are actually diagnosed with think about it all even though we all are different xxx
