What’s going on with my body?!

So back story, I’ve moved out and been moved out and in with my bf for 3 months now. Been extremely stressful so yes I have considered this as my reason. But! I hadn’t had a period for 75 days. Last night, I was in extreme (like bring you to the floor pain) in my ovaries, pelvis, and abdomen and sciatic nerve (which I’ve always had, it’s just been getting worse lately.) it was a constant pain that sometimes came in waves ...not really sharp pain but extreme pressure that hurt horribly!

My boyfriend and I have sex maybe 2-3 times a day...everyday. And that’s not an exaggeration. I took 2 pregnancy tests today...negative. We don’t use protection and he doesn’t pull out, there have been MANY times I should have gotten pregnant, but every time I take a test they’re negative. (Don’t get me wrong, I don’t want a kid now, but I wouldn’t mind it and it wouldn’t be horrible) but I can’t help but feel discouraged when they come out negative. I don’t even take birth control anymore bc I gain too much weight. Anyways, after the test I started my period. Or I thought I did, it went away after 30 minutes completely. 😭

I’m beginning to think I can’t get pregnant and that’s scary for me. Bc my biggest dream, being able to carry my own child and birth a child of my own. My periods have always been irregular. But this was possibly the longest time I’ve gone without having a period since I got off the nexplanon implant. (2 years!) 75 days. All I can chalk this up to is last nights pain was PMS and now I bled for 30 min and it’s over. What do you guys think.
