No idea when I ovulate

I did an ovulation test at the start of the weeks and both lines were same colour

DTD the previous night and that night and the night after and this morning so I’m covered

But I really have no idea

I had the implant and then the coil so not actually had a period in a very long time !

I have my coil removed 16 days ago

Two days after I started bleeding heavily and that finally stopped after about 10 days

No idea if it was a period or withdrawal bleed because I’d say I was due a period as my boobs were sore before I had it out

I’ve tried looking at ovulation apps and done tests but feel like it’s just stressing me out because I really have no idea

I have two children already and I never did this with them

Just let it happen

Both were conceived very quickly my youngest was literally first time

So I feel like I should relax and let nature take its course

As long as we’re having sex every 2-3 days when not bleeding I’m covered ?
