TTC Symptoms?

Reese
Normally my PMS symptoms are very light cramps and bloatedness around 3 days before my period should start. Usually sometime within the week before AF hits I just have the feeling, like a feeling that my entire body is preparing for AF but those are my only symptoms. Then I get it and I have really bad cramps the first two days and then nothing but bleeding for 3ish more.
So knowing that, I am due for AF in 4 days. In the past two weeks I've had nausea, backs aches, bloating everywhere, tightness in my tummy, waking up at night to pee, headaches, and I've been an emotional wreck. This may sound silly, but because I'm actively TTC and I've changed my diet (quit caffeine/coffee cold turkey) could that mean my PMS symptoms have just evolved? Could I be experiencing something other than pregnancy?
