Cramping 5dp5dt

Desire
I'm having some semi decent cramping today.. I honestly hate this.. my boobs are on and off sore.. I have no def signs though 
I've read online the hcg trigger shot is out in 8-10 days.. some say 14.. some say the got their bfp around day 12-13. I'm just frustrated!! Why isn't this black and white?!
