Okay so I'm 2 weeks late as of today and my periods are usually pretty regular with the exceptional 1-3 days off. My cycle is usually 23-25 days sometimes 28 days. The last time I had sex was January 4th. My last period was Dec 8th and the last time I had sex before January 4th was November 21st. I'm going to take a test but I'm just wondering if it sounds like I am pregnant or if it could be something else? Should I be worried?
