Question!!!! Need answers fast

Info: I had a my very first deposit shot five months ago and never went back to get another one. So now my periods varies, this time I spotted and the color was different brown and pink, it lasted few days. I do feel nausea and having small stomach pain, headaches and backaches and having strong vivid prego dreams.......

The past few days My cervical mucus been creamy and later be watery all in the SAME day. My underwear will have wet spots all over. What does this mean???? I know what each mucus mean but never had two in one day or have wet spots on my underwear or feel super wet even after I wipe after I pee (SORRY FOR THE TMI) and I feel like something coming out of me like pee but doesn't look like pee or smells.
