TMI: Period or pregnancy

I’m not trying to conceive, but not preventing it either. My period is due today or Tomorrow, I had brown discharge/spotting when wiping maybe 3/4 times yesterday, which I had when I found out I was pregnant with my daughter. Im 10 dpo according to my period app. We had intercourse last night, so I was expecting to full out bleed or something afterwards but it’s quit, then some very light pink spotting/ blood tinged discharge when wiping today

. Is this normal to have right before a period because I usually just full out start or could it be implantation bleeding. Never had this before other than when I was pregnant. 😬
