Am impregnating????!!!! Pls give me as much advice !!

On oct 24 2019, I had protected sex with my boyfriend but we were afraid maybe one of the condoms broke when he came , do the next day I took a plan b and I was ovulating around that time. So 2 weeks later after my period, it had clots and was red but kinda light and short like how plan b described. But before my period came I had unprotected sex at Nov 2 but he pulled out way before in time and nov 3 was protected. And after that I’ve been having pregnancy symptoms, my stomach is cramping, nauseous , fatigue , I’m stressed. And my discharge also stopped coming ( it was just a watery texture) but today my discharge came back, my cramping hard , I have as headache, I’m breaking out . Could it be my period coming ??? ( I also had protected sex on the 29th but we were safe nothing broke :) I’m hopin my period might come. Could’ve nov 2 and nov 3 affect it all ? Or I had my period already so it couldn’t ? ( also what does does implantation start ? Cause I’m afraid it’s probably that cause it started 14 days after ovulation )
