Period is late, worried I may be pregnant

Hi, I'm 25 years old and have been sexually active with my fiance and we always use a condom. Last time I had sex though was Feb. 26. and at first, we didn’t use a condom but we put a condom on before he ejaculated. My last period was from Feb. 2 – Feb. 6 and it’s already been 34 days and I’m worried I may be pregnant. My average cycle is about 30 days. I was wondering if it was normal to be a little late on your period. I have had the same diet for a while, been working out at the gym at least 3 times a week, everything should be normal unless I’m just stressing over it. My stomach has been feeling weird lately, maybe because I'm nervous I don't know. I haven't had any food cravings, no discharge, no lower back ache, no cramps, and my breasts are not tender or sore.

I'm not on birth control yet but plan on getting them after my next period. I'm anxiosly waiting for my period. I am not ready to be pregnant.
