I need help...🥺

According to this app I’m 22 days late. I’ve taken test after test and it’s negative. My last menstrual cycle was 13 days. It was long because, it was my first period after the depo-provera birth control shot, but I quit taking birth control in hopes to get my cycle back because it felt weird to not have a cycle. It was dark brown and sometimes red, but mostly brown and not very heavy I’d say medium flow. I’ve never been late, I usually have a regular menstrual. I haven’t had signs of a period besides my breasts hurting, they’ve been hurting really bad. I haven’t been spotting or anything like I’m trying to start my cycle. I’ve had some cramps in my vaginal area no spotting not even a little sign of blood, I’ve been having clear/egg white discharge as well, but no spotting or blood or anything. I just don’t know what’s happening and I’m wondering has this ever happened to you? Do y’all think I could be pregnant? it’s just not showing up on the tests yet? I mean if I’m not pregnant when will my cycle come back? I’m just worried because I do want to have children in the future and I feel like I’ve messed myself up by taking birth control and switching birth control trying to find the right one. I
