I have pressure in my pelvic area, my vagina has become too tight for intercourse, have been vomiting and spotting for a few days now. pregnant?

Hard to guess: For fertile women who are having sex... it can be hard to tell if a woman is pregnant at the beginning of a pregnancy. A home urine pregnancy test gives a accurate result. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), 1 week after missing a period, or 1 week after starting a "weird" period. If having worrisome symptoms, an Ob-Gyn doctor can examine.
