Opk help!

I took my first round of Femara this month for PCOS and have never had a + opk. These are from yesterday, this morning with fmu and this afternoon. How close do y'all think I am to "O"? Today I've been having period like cramps on my right side, I feel pretty bloated and my boobs are sore. Being as I have never ovulated idk the difference in ovulation signs and pre-period signs🙈 what do y'all think?
