is this my period?!?

i always start my period on the tuesday of my placebo pill week. i have been on birth control for almost a year. my period is usually a medium flow and everything. so i’ve been getting this since tuesday. brown discharge and light red bleeding. it’s very light!! wednesday it was starting to get heavier, so i put a tampon in and it filled it up then it stop at 3pm and started to be really light again. i took a cotton swab and swabbed up there tonight (thursday) (ik that’s weird but toilet paper wasn’t showing nothing) it showed like a regular period blood color but it’s really light. i do have sex and we always use condoms. the last time we had sex was december 31st and we didn’t use a condom. we tried it for like not even 2 minutes and i stopped bc i felt uncomfortable and unsafe without a condom. he came way after that tho bc we did other stuff so i don’t think i could be pregnant. i have never missed a pill either. i’m just nervous :( idk what’s going on!!! (the first picture is from tuesday, next two is wednesday and then the last 3 is from today)
