What’s going on?

My period is 11 days late according to Flo. I took two pregnancy tests 5 days ago and both were negative. I do have PCOS so my periods are irregular and I’ve been taking Levothyroxin and Metformin for the past almost two months.

I did stop taking both for a few days end of October, but I’m now back on them. I’ve been having cramps everyday that feels like my period is coming, but nothing yet.

We always use a condom and we always check it, the only time I forgot to check it was on October 21, but he said he did and it was fine.

Am I pregnant? Are the meds effecting my cycle? Is it even possible to be pregnant right now or have symptoms of pregnancy from October 21 or is it too early?
