what does this mean? *TMI*

Hi ladies ! I’ve been having a little trouble so i wanna see if yall could help me out.. so i am currently sexual active and me and my boyfriend had unprotected sex about 2 weeks ago .. i recently was diagnosed with bv about a week after that i started taking vaginal gel to get rid of the infection. we had unprotected sex again and then couple days after i started having abnormal spotting .. it goes from rust color, to brown spotting with red stringy blood, to pinkish brown spotting, to watery brown discharge, to light red spotting .. its confusing and its not enough to where i need to wear a pad or tampon. but its been going on for about a week now. my appointment at my ongyn is on wednesday and i got told i could be pregnant but im not so sure because my periods are beyond irregular! my last one was april 13th. what do you guys think? i left some pictures below to show what my discharge has been looking like.

i only used a tampon once because i was wearing my fav underwear and some spotting was getting on it 😂

***BTW .. i only had that last weird looking picture of discharge once and that was the first day i noticed this discharge that occurs only when i wipe. these past couple days its been looking like the first one and light in color from pink and brown to light red and sometimes watery.
