IDK What to do

So two days ago I was 10 days late for my period, I started seeing a little blood but it’s not heavy enough to be my period ( I think). It was only when I wiped after urinating, I’d see a small patch of blood (small like a coin, faded red). I thought I was starting to get it but today is the 13th day and I’m still not getting much blood. After a few hours I check my pad and it’s brown (old blood) and nothing else.

I have been TTC for a few months now but with my PCOS, I really don’t want to test for pregnancy due to depressing thoughts emerging if it is Negative 😭

I would like some insight into this please. Am I overthinking and slowly getting my period, like should I start counting my days for my period? Or should I just go doctors and check...... I also hate the doctors they tell me the same sh#t all the time..... loose weight..... but I have been, I’ve lost 20kg already 🤦🏽‍♀️ So I’m really fed up with their so called ‘PCOS’ Diagnosis and just want to have babies 😭😭😭

UPDATE: I forgot to mention that my periods are not irregular. I get them every month and for 5 days. I’ve decided not to take medication and attempt to fight PCOS with a healthy no carb diet and nil processed sugar.
