I Think I'm Having A Cryptic Pregnancy And If So

I think I'm having a cryptic pregnancy and if so then I'm 22weeks along. This month I had my cycle around the 11th stayed on it as usual, ended it and started again on the 25th. I feel pressure , lots of discomfort, and my left side of my tummy is two inches bigger than my right side. I'm scared to go get checked but I can t take the pain and discomfort anymore.its been going on for about a week now. My pain level is only at a 6 or 7 but my discomfort is at a 10 and won't go away. I'm afraid if I go in they won't bother checking me if I'm pregnate just because I've had my periods all this time.
