Ughhh

Had spotting november 23rd, took hpt last sunday & got a faint positive ! Im now 5 days late for AF & im NEVER this late ! I have major headaches, nausea on & off & my boobs feel heavier. Took a first response this morning & it was negative so WTF ?! I have no signs or symptoms of AF coming & my cervix is extremely high. I just wish i knew WTF was really going on. & to top it off me & SO split up this morning 😫
