12 dpo and going to rip someone's head off?

My boobs have hurt since 3 dpo (w/ increased Femara and IUI), having occasional cramps, bloating, fatigue (haven't slept through the night in 5 days), creamy cm and way more cranky then usual w/ pms. Now my temp is spiking. Sat on my bathroom floor weeping yesterday which is totally not me! AF due on Thursday. I'm not into the charting/temping thing but wondering if anyone else gets a temp spike before af comes or if I could be prego. Tested w/ a really sensitive test and was negative. Hating how these symptoms could be either/or!!!
