Trying for baby number 2

Hi all I’m looking for some advice I have a beautiful daughter who is going to be 7 tomorrow (how time flys only seems like yesterday I gave birth) me and my partner are trying for a baby together (he’s not my daughters dad)

I had the implant for 6 years had it taken out few months ago as had run out previous year took a while to get appointment to have it removed

My periods where regular at one point but for almost a year they have become irregular some ones I have 2 periods some months I go without one and other months I’m on for like 16 days I have had tests done and everything came back normal but not pregnant as yet

As any of u lady’s been threw similar things and got pregnant if so could u give me some advice please

Thank you
