PCOS & BFN

I need help from other ladies with PCOS. I only get my period 3-4 times a year. Never been regular so I can't track pregnancy with that. Since August 22 my husband and I have been TTC. I took two tests yesterday and one today. They all were BFNs, but I feel like crap. I've been nauseous, bloated, had tender boobs/nipples, slight cramps, sore ribs, lower back pain, super fatigued, increased acne, and just feeling uncomfortable in my lower abdomen. Idk. Having that many negative tests makes me pretty convinced I'm not, but idk. Is there still a possibility? Do you have any other idea of what it could be?

Please don't talk to me like I'm stupid. I know a BFN basically means no. But these feelings/symptoms are just unexplainable and I need other ladies to give me opinions.
