Implantation bleeding, ovulation bleeding

Arianna

So I recently had my period and it was pretty lighter than normal but lasted the same amount of days. I stopped taking my bc because I never took it at the same time everyday. But my last period ended oct. 28th I’ve had sex before my period and after my period and on the 30th. I kept feeling like a car sick nauseous and I was super emotional during my period which isn’t normal I’ve felt like I gained weight. Yesterday on nov.4 I took a test and it was negative. Randomly today I’m spotting. What does any of this mean? Because the test was negative yesterday and my next period isn’t until the 24th and it says this week is my ovulation week
