What in the world?! Can someone give me some advice??

So I’ve been ttc with my husband for almost 2 years now and no luck. My period is irregular but not to the point where I miss it months at a time it’s usually just a couple days off every time I get it. Well this app said I should have gotten my period 15 days ago and haven’t taken a test since the first or second day of my missed which came back bfn. I really haven’t wanted to test again because these constant negatives make me really depressed and I’m trying to keep happy thoughts. Well to add to the suspense of my missing Aunt Flo yesterday I started getting this really bad cramp/pain right where my pelvis meets my torso on the right hand side. I’m worried it might be a cyst or something because it comes and goes but if I bend weird or move in a certain way it feels like something inside of me is going to burst. I don’t have insurance so can’t go to the doctor and really don’t want to go to the hospital unless the pin is unbearable. Just wondering if you lovely ladies have ever experienced anything similar and if so please share. Sorry for the long post and thanks in advance for any help.
