Help!!??

So I’ve noticed this sunday morning morning that i’m having some pinkish/red discharge and it’s thin not so thick like period blood. I just had my period Last saturday the 27th, and my next isn’t until around the 19th... now for the past few nights i have used some suppositories and i used the insert thingy. and thursday night (the first night i inserted the suppository) i was experiencing some major itchiness and the following morning as well but after showering friday night and doing my second insert it went away. now i’m experiencing some slight cramps along with this red discharge. but i recently used these same suppositories the week before my period started and had no symptoms of the sort, but again i didn’t use the insert thing neither. ofc i took to google and mostly it stated its just spotting after or before a period, or implantation bleeding but i’m definitely on birth control. should i be alarmed? i have no other symptoms besides cramps that feel like my normal menstrual cramps and the thin pinkish/red discharge. no burning sensation, no more itchiness, no irritation or nothing.
