I'm 23,married and mother of two. My husband had a vasectomy 3 and half years ago. I am 2 weeks late. I experienced a light brown discharge a few days ago for just one day, alittle nausea, breasts feel heavier than usual,got PMS like cramps when I was supposed to get my period,pressure in lower left side of abdomen, and frequent urination. I have not taken a home pregnancy test yet(scared). Any explanation for these symptoms? Any answers would help.
