Should I test?

I have pcos and I’m over weight which makes it harder for me to get pregnant🤦🏾‍♀️ but my cycle is mostly regular it is 34 days long once it lasted 40 days well today is cycle day 36 which makes me 2 days late but I always know when it’s coming bc I always have cramps but I don’t have any pms symptoms like usual. I only have swollen breast but no pain and I’ve been more sleepy than normal I haven’t been eating much like I usually do when I pms so should I take one? And I have been taking fertility pills earlier this month and had sex during my fertile days
