PMS spotting?? Please help

SOS. So the app says I’m supposed to get my period in 7 days, but I have 2 pills left in my BC packet. I’ve been spotting these past 4 days and had protected sex(condom and pill) like 2 times a week ago. My boyfriend did cum in the condom but there didn’t seem to be any leaks when he pulled out. I did end up doubling up on pills maybe 2 times this month? Could it just be spotting because of that? Just want some opinions that this is spotting and not implantation bleeding. I absolutely do not want to get pregnant right now. I’m a bit of a hypochondriac and have been having tender/sore breasts, cramps, headaches etc. so of course when I googled it lots of pregnancy info comes up so I’m super paranoid now. The blood will also range from brownish to this color. I’m scheduling a gyno appointment but really just need opinions/advice on this right now. Anything helps!
