HELP! LADIES I THINK IM OVULATING FINALLY!!!

Im on metformin 1000mg and Femara 5mg 5-9 and todays CD10 i thought it was too early to ovulate but im a little crampy but got these!!! I had gotten off birth control and didnt have a period or never had a positive opk in those 6 months. They were all always dark but never darker than. Are these dark enough? Isnt CD10 too early to be ovulating when i took the feamra 5-9

Side note i only had the tinest bit of urine to test with because i had just went to the bathroom and forgot to test so i managed to get a little bit of urine like 15 minutes later so maybe it wasnt that potent either and it could be darker when i test again in a few hours
