I need help/guidance please

So we’ve been ttc for 7 months and Iv been using opk’s, keeping an eye on cervical mucus etc but this month thought I’d try bbt tracking, it confuses the hell out of me but this month I’m even more confused because for the first month ever Iv not had a positive opk

I def think this is down to the face that Iv massively upped my water intake so my urine is always pretty diluted.

Can someone look at my chart and see if you can guide me....I had been marking my opks but have deleted them as it kept shifting my predicted ovulation day and was confusing me more

Thanks in advance, please be kind to me I just can’t get my head around this charting malarkey 😂
