Odd Spotting Since Off the Pill-Trying To Conceive

I went off the pill in July and spotted for over a week before period due, about two weeks into cycle, it was pinkish orange tinged and didn't end until period started (spotting didn't really stop, wasn't heavy, more noticeable when wipe). The second month pretty much the same thing happened & cycle started when expected and regular.

Now I am on the third month, spotting started again about 12 days before expected period, but this time started with tiny streak of red in cervical mucous roughly once a day for three days and twice I had wet spots in undies like I peed a little with tiny spot in middle. Then spotting started to be thicker cervical mucous with pink, orange & yellow. This only lasted within a span of 5 days and ended with very light brown spotting like the end of a period. For two days during spot I had cramping in lower back, which I don't recall during spotting on months 1 and 2.

Called nurse to see if I should get checked out last month, she told me to wait one or two months and see if it stops.

I've had cysts and a fibroid identified in ultrasound a few years back, but at last one the tech said she didn't see anything.

So, I am wondering are these three months just my body getting back to normal after the pill, is it spotting and pain from a cyst or does the third month sound like implantation bleeding? Spotting stopped 4 days ago, period is due 4-5 days from now. I tested a few days ago cuz I can't help myself : ) it was negative, it would be too early anyways.
