Pregnancy or crazy PMS?

So for this past week, My breasts have been sore and swollen, my nipples are bigger and a bit darker, I'm extremely tired- like nodding off in conversations- I'm constipated lol we went to see the new Tarzan and I cried through the entire thing. My skin looks gross, I feel nauseous (only for a few seconds here and there) and I have 0 sex drive whatsoever. Like the thought just repulses me lately. and I'm super moody. Lol AND, it's only been today, but I've had to pee every hour or hour and a half. My dog has also been super clingy these last 5 days. Following me and has to be touching me constantly. Also, my boyfriend is super adament about condoms but usually he doesn't wear one to start; but always finishes with one.

**sidenote- my period isn't due until the 23rd**

Sorry there's so much gross detail lol I'm just confused!!
