Could this be implantation bleeding or just an early period? 🤔

Okay, so my spouse and I have been agressively trying to conceive. We had intercourse my entire ovulation period, multiple times before and after ovulation. Now I'm scheduled to have my period 4 days from now and I am ALWAYS ON TIME, maybe a day late at the most. Since ovulation, I've had frequent urination, been very fatigue, nauseous, constipated and a bit bloated. Now today I had some extremely light bleeding or spotting wit a bit of discharge in what seems to resemble implantation. Could I be pregnant?  🤔🎉😁😊
