I need some advice what is the best thing to use to help regulate my periods I have irregular periods and its annoying I've been caught 2x but ended in miscarriages, me and my partner are "having fun again" I've been doing opk tests but its starting to frustrate me as I'm confused with them and I don't know how to read them as the 2x I've been pregnant that's without tracking anything just baby danced every other night and bam preggers but I had a miscarriage 3 weeks ago and the last 6days I've used opk and not even a positive yet please help and explain to me on the opk work 😫 I sound so stupid, whens the best time to test in the morning or the afternoon? I seem to have them abit darker in the afternoon as I done 2 in the morning or it might just be me πŸ€¦β€β™€οΈ

I have attached a photo of my opk the past 6 days
