I have no clue...

Not sure what is going on with my body!!! Glow said my fertile window was over yesterday, but also said it started the day after AF left. My boobs have felt a tiny bit achy, very mild cramping, and now I am getting those dull aches in my vagina. Has anyone else had any of these happen? I've been TTC 3 months and had Mirena removed in Feb. after 8 total years of having it.
