I'm just...lost

I hate being irregular! I never know what's going on with my body 😭 I had a normal period October 14-18. I then started to spot brown October 29th-november 2nd 🤷 I then started having major pregnancy symptoms about a week ago. So I tested, 2 blue dyes had faint positives but I know those tests suck. So I tested with Walmart cheepies, negative. It's now November 17th and I'm spotting the same brown stuff as I did last month. It's like really dark brown cervical mucas (not a lot). I am cramping and my pregnancy symptoms have gone away, except my boobs hurt, itch and have gotten bigger. 😓 I don't know if this is my period or just random spotting. 😭
