Possibly pregnant again?

Okay so I guess i’m just kinda looking for opinions.

I haven’t been able to get birth control yet because my insurance has been all messed up so i’ve been SOOOOO careful when having sex, I make him wrap it every single time, I don’t even let him come near me without a condom 😂 but I just had some spotting a little bit ago.. and the only time that has happened was when I found out I was pregnant with my first baby. I haven’t had any other pregnancy symptoms that I had with my first, I have been tired, emotional, and I just started having back pain.. but that usually happens before my period. My periods are still pretty irregular ( I had my baby almost 8 months ago ) so I don’t know if i’m late lol. I’m just really confused by the spotting! I’ve never spotted before my period, but i’ve also never really paid as much attention lmao. I’ll be going to get a pregnant test soon but please ease my mind in the meantime 😂
