Could I Be Pregnant Despite PMS Symptoms, Given A 14-day Delayed Period And Protected Sex?

14 days delayed period. Had protected sex using condom 3 weeks prior, checked for holes but there were none. Took the PT at the 6th day of late period turned out negative. Experiencing PMS such as headaches, sore breasts, cramps. I have an irregular period with 30-35 days cycle. Is there a chance I’m pregnant?
