Missed period

Taylor

Wondering if anyone has experienced this? My last period was in April if this year. I assumed my period was late because I was stressed about moving in May. I’ve taken multiple preg tests and they are always negative. I had no other symptoms until November, I started spotting 1 day a week for a couple weeks and then it picked and became everyday. I would spot for a couple days and then it would stop. Does anyone know what this could be? I’m think it has to do with me being over weight and gaining so much weight this year. I know I need to go to the doctor but I just got health insurance this week and have to wait until I get paid again to go. Anything would help, thanks!
