PMS identical to Pregnancy symptoms

Mags • Veteran & military spouse. Obsessed with our dog and our cat is an asshole.
Does anyone else deal with this? I'm a year off of the pill now and every month, exactly two weeks before I get my period, I get every symptom in the book for early pregnancy.
Let me tell ya, the negative tests/exactly on time periods are really starting to irk me and my overly sore boobs.
Symptoms:
Excess saliva
Crazy sex drive
Exhaustion
Hormonal acne
Nausea
Cramps
And my poor, swollen, pained boobs. 
Seriously, two weeks of feeling fit as a fiddle and then BAM. Like clockwork.
Is anyone else like this?  Or is there a reason?? I have been on the pill for my entire adult life, so this year off of it has been a new experience.
