HELP TTC, Could I be pregnant?

Brianna

Me and my fiancee have been trying for baby number 1 for a couple months now and my cycle is super irregular but in January I learned that I had an ectopic pregnancy and it had to be removed via medication since we caught it early enough, since then I've gotten the depo shot twice and this month is the month I'm supposed to go get another shot but Im letting it wear off so for the past couple of days I've been having a lot of pregnancy symptoms (sorry tmi in advance) including: Cramps

Light brown discharge and Creamy white discharge

Fatigue

Diarrhea

Nausea

Gas

Bloating

Food Cravings

But today my light brown discharge turned bright red! Its not heavy enough for a pad and Ive had on the same panty lined on for hours since it started but its not getting on it, its only noticeable when I wipe, i had a light brown to red back to light brown spotting "period" already this month and i would like to know could I be pregnant or could these be signs that the depo shot is wearing off??? I'm going to take a test if AF doesn't come tomorrow or soon, share your stories & baby dust to all 😘😘😘
