No period, no pregnancy, what’s up

I’m 26 years old to start off with.

So, I am pretty irregular to begin with. My cycles vary between 28-35 days on average, typically closer to 30.

Well, my current cycle is on day 41. I’ve only had two cycles outside of my normal, and the other ones involved taking plan B, the longest being 48 days as a result of taking plan B.

I’ve taken two pregnancy tests so far and they both are negative.

I’m not sure what is going on with me at this point?

I don’t take birth control. I have children, the youngest is 4.

I do have PCOS, but it’s never really effected my period to this extent. I honestly don’t know.

Any advice or suggestions would be appreciated cause, I’m not sure what to do or where to go to actually talk to because I don’t have insurance anymore thanks to covid 🥲
