Ovulation tests for pregnancy test

Kc • 24, been TTC for 3 yrs, diagnosed with PCOS
So I have read that you can take a ovulation test as a pregnancy test since lh and hcg are almost identical. (But not 100% reliable) So af is due in 2 days according to glow.. So I took a opk (have yet to buy any hpt) and it was positive.. Lol what you ladies think? Possibly a good sign? Boobs tender, been tired (could be cuz I'm sick tho) let me know your opinions 😊😊
