I’m new to this please help!

Today I start my first tww!! I’m so excited but so nervous, I’m already driving myself nuts looking things up. I’m honestly not even sure if I ovulated or not. I had a lot of watery cm starting 4 days after my last period and that continued through my fertile window, I had no EWCM but I read that watery cm is also fertile. I had a couple ‘twinges’ in my right side a few days ago and yesterday (my expected ovulation day) I had light cramps in my right side and in my lower back for about an hour, not sure why? I know the odds of me actually getting a bfp are probably pretty slim. I’m wondering if maybe I ovulated before my expected ovulated date? (I know it’s just a guess) I’m totally new to this and can’t really find anything on google. Any helpful advice or insight??
