Need help...PMS or preg symptoms

I am new in TTC and this is my 3rd month of TTC. we BD a lot during my fertile window. My expected period date is in 2 days which I obviously don't want it to come. On Saturday i had a dull cramp and queasy stomach. yesterday the cramps were full on for about 30 40 mins and then they vanished. I literally thought that periods have come

I just want to know whether these are normal symptoms or not.

I have not yet taken a test because I m scared of a BFN
