Exhausted, need advice about irregular cycle 😒

I had Mirena removed 4/30, DH and I are TTC a third child. As you can see by the calendar, my cycle is a mess. The first few days I blamed spotting on the removal, but almost every day now for two weeks has been either pink/brown spotting or bouts of actual period blood - but nothing big and certainly not consistent. I've had maybe one day "off" from it. I've done opk testing all but a couple days, last Sunday and Monday it looked like I was maybe having an LH hormone surge. But now I'm skeptical because of all of this random bleeding. I've had the IUD for close to ten years, so I don't remember anything about my cycle; how many days it is, how many days I bleed, etc. This is all so strange and new and I'm so frustrated already. Can anyone shed light on this? I'd be so grateful, I feel really alone right now and DH is trying to be supportive but if I don't know what's up with my body, he sure won't. πŸ˜’
