It can be completely normal. And defiant could be since ttc you're noticing more. I spot some months before af and it send me crazy cos I think it's implantation bleeding lol. I had a copper coil and irregular periods and would spot randomly all the time then and when I had both types of the pill. Especially the one you take continously with no break I'd have maybe light spotting at a time I would know of I wasn't taking the pill my period would be due.
Sometimes spotting can be implantation and again completely normal.
From my experience, I'd get spotting checked out if it's accompanied by severe pain. I have painful periods I need codeine for but the pain from implantation right through till surgery for my ectopic was way worse now I look back I think I should have queried earlier due to the pain along side spotting.
I don't mean cramps though. I also get cramps during ovulation and ovbs period and spotting with cramps for me is normal.
