Implantation bleeding

Megan

TTC and had sex three days in a row around ovulation day. We use ovulation strips and we got a very clear positive result. I’m due for my period on 8/26 according the app and tracking my last two cycles. Yesterday, two days before my period is expected, I started bleeding. Brown blood when I dabbed down there, some red blood dripping into toilet with bowel movements. I figured it’s my period that came a little earlier than expected. I put a panty liner on and it had some pink watery like discharge on it by end of day, not much at all. Next pad had tiny amount of brown discharge. Didn’t bleed much through night but dripped some red blood into toilet with morning pee today. Put a tampon in expecting heavy flow, removed a few hours later with small amount of brown pink discharge. Put a pad on for the day, hardly any blood on it. So I’m fully expecting this to be my period. But what’s strange is usually days 2 and 3 of my period are hell. Heavy bleeding, severe bloating, terrible cramps and pressure in my lower abdomen, acne, mood swings. I have none of those symptoms. I feel some twinges here and there in my uterus but that’s it and my face has even cleared up. Anyone else experience this before a positive pregnancy test? Could this just be implantation bleeding?
