Been moody more than usual very fatigue my lower back is killing plus cramps my hips have been hurting and having headaches I got off my period on August 19th which my period was weird anyways my period lasted 3 days then off one day then spotted the rest which was very light pink.

I keep having the cramps in my uterus and pelvic area along with my hips. Has anyone went thru this before they found out they were pregnant? I’ve been having really bad baby fever the last couple weeks and I don’t usually.
