Stress related?

Okay, so Ive had a pretty stressful past couple of weeks. I lost my job (and thus my health insurance), stressed out hardcore, found a new job, found out after I got new said job that it doesnt provide insurance, got insurance, insurance got messed up somehow and now I have to wait til Monday to fix it, and had an interview for a second job to help cover costs, but am anxiously waiting for a call back, and Im planning my wedding on top of all of this. Ive never had a regular period cycle, most are somewhere around 35 days give or take a few days. Im on day 40 now. I had sex the week after my last period, but used a condom and he pulled out. Could I be not getting my period because Ive been so stressed lately, even if I dont feel it all the time?
