TTC newby needing some advice 😔

Okay so I’ve been on the pill for as long as I can remember and me and my husband have decided to try for our first baby! I came off my pill at the beginning of February and had spotting for a few days after about a week of stopping. my periods came back at the start of March (4th) and again at the end (30th) both only lasting 4 days. I’m literally becoming obsessed with tracking my periods to see when I’m fertile and have a bunch of apps to try and help however they all say different dates for ovulation and I’ve never been very good at tracking my body like I don’t feel any different during my fertile window than I would any normal day, my CM is always pretty watery with the odd white stuff present but never a lot of it. Any advice on what I’m meant to be looking out for? I honestly feel like I’m just not ovulating at all and I’m just waiting for AF every month and getting slapped with that BFN 😔
