Hey girls just asking for some advise.

My husband and I have started trying for baby #1 about 2 months ago, I got some light spotting Saturday (roughly 12 dpo), I only saw it when I wiped, it did get abit heavier the following day although not enough to fill a pad and then back to light spotting and now nothing. I thought at first it was my period but it was such an unusual period for me, I hardly ever spot, it’s usually heavy at first and I had no cramps or back pain which always comes with my monthly flow 😂 I took a pregnancy test 3 days after the start of my spotting to check. Could this be implantation bleeding or probably period? What’s your experiences?
