What's wrong with me.

Okay so, I'll have pictures below, but long story short, I have normally long cycles, nothing new, but I have now completely missed 2 periods. My husband and I bd a lot, I tracked my cm and thought I had it right. I thought this month was my month! I have been(all symptoms are still happening) vomiting in the middle of the night, and so nauseous threw the day. I have to pee an unusual amount of times. Head aches like no other and I'm usually not the one to get head aches ever? Every little thing I do is taking my breath away, taking a 2liter up maybe 15 steps wore me out. And I pour sweat more than ever in my life. My nipples are sore, and I can't shake the initial feeling that I am pregnant! I've taken 2 home test, both were negative and I took them a week apart. Keep testing or see my doctor?? Do you think it's all In my head?? Anyone else had similar things?
