Implantation or period?

Tomorrow is my period. I have been having cramps really bad like for a week. And I went to pee and I see this. I've heard of implantation before and they say it's usually pink. Well this happened to me last month too but a little bit heavier like the day before my period but a panty liner is enough then the nxt day it was a lot heavier like i needed to wear a pad. Yes I am sexually active but me and my bf always use condoms. We don't ever have sex without one. We mess around without one but my bf never gets to the point of cumming. And he knows when he pre cums and at first I didn't believe him till he showed me 2 days ago. We were in the bathroom and he said he's pre cumming and I looked and there was nothing and he said just wait and there it was his pre cum so now I believe him. So there's no possible way this is implantation bleeding. We don't ever have sex on my fertile week and on my ovulating days. And I have taken 2 plan b pills on March and April Bc of an incident and I've researched that it takes about 3 months to get my cycle back to normal. Since last month was my first period after plan b it was pretty weird it was early when usually it's always late and first day was light when usually it's like gushing blood everywhere for me. So please let me know yall's opinion!!
