Implantation/Spotting

I had spotting this morning only 2 weeks after my last period finished, wondering if that's too early for implantation? I'd upload a photo but it was on my liner this morning after sex last night mixed with cum so lol don't suppose it's from sex?

I had a miscarriage late November/early Decmember and my periods are still adjusting. I haven't bothered tracking ovulation because my tests were all over the place when I was tracking recently. (Multiple negative, positive, peak, back to negative throughout the month)
