I am so confused!? This is gonna be a long one. Okay so I had my period last month on the 19th, it only lasted 3 or 4 days and it was lighter than usual, then I started having literally every single pregnancy symptom there is and I still am, I feel like I can feel my uterus right above my pelvic bone like it's hard right in the middle, but I just started my period 3 days ago.... It was a light pink at first and really light and then it got heavier and is a dark red now like a normal period. but it's not nearly as heavy as I normally am... could I still be pregnant? or no? I'm so confused...
