Implantation bleeding or super early period

Kendall • 2.5 year old 👦🏼 • ttc 🌈 1.5 years

Im supposed to start my period in 17 days. Ovulating this week. We had sex on April 1st(ovulating), 11th, 27th and May 1st. Today I noticed dark blood in my underwear. Could this be implantation..?

My periods usually aren’t this early and I don’t have the typical period symptoms. TTC baby #2
