Mental health or PMDD?

I’ve had anxiety and depression for like 5 years solid now and finally finding a good SNRI it has helped significantly.

But I would still experience what I believed to be OCD as it was separate from my anxiety. Angry, rage full, harmful, REPETITIVE intrusive thoughts that are extremely angry and just flood into my head. Extreme irrational irritability. Some rumination, how I check everything. Over analyse for hours and create notes for each little thing with sub notes etc.

After a while, I started to notice it tended to be just before my period the majority of the time so my doctor prescribed me Pyridoxine which is like a high dose of vitamin B6 I believe. He said it sounded like pre-menstrual tension syndrome.

Since then I’ve not really had an attack of these thoughts and it’s really confusing me because could I still possibly have OCD? or was it PMDD all along?

Honestly, everything overlaps so much that I’m struggling to figure out what’s what.
