Help me

So I had my implant removed last month on the 28th April and I was meant to get it removed four years ago but I don’t know if it had drugs in the implant still, umm it made my periods irregular for a while and I had sex in February and all pregnancy tests are negative (done loads throughout the couple of weeks), I last had my irregular period with the implant in that ran out of date and needed to be removed was on 27th February 2022.

I had it removed last month and I have not had a period whilst not having the implant in my arm and I had sex last night and I did a ovulation test this afternoon and I know it’s not near but I think I’m about to ovulate nearer to the end of the month.
