Pregnant or not???

Hi all

I am 36y old , with a history of PCOS. However, since past 2 years I have been getting quite regular periods.

We have been ttc since past 4 months only, my periods are 8 days late today. I am having cramps just like the period, frequent urination however don’t have any other symptoms as such. My diet hasn’t been great in past 4-5 weeks, I have been eating a lot of high sugar high carb foods and have gained around 3kg weight in the past 1-2 months.

I am just a bit confused as to wether I could be pregnant, or it’s related to PCOS relapse !

Would really appreciate your thoughts!

Thank you
