Generally my internal clock doesn't falter, my chart is always on time. I had unprotected sex (he pulled out then immediately went back in about four times) on the 16th day of my cycle, and my period came ten days later than anticipated and was incredibly short and light for me. (i am currently in limbo until the end of the month when my next period is due) I have recently been having issues with carsickness, sore and leaky breasts, mood swings, loss of appetite, and exhaustion. The man I had been seeing recently broke up with me so I am worried about making this a big deal and having him take me to get a test if it's normal and nothing to worry about. Has anyone had this happen to them? Can this just be a general twerky menstrual cycle or does it sound more like pregnancy? Any advice is appreciated.
