Ok, I had sex on May 20th, May 29th I had a heavier than normal period. June 9th had sex again, and now June 26th I am spotting these three colors with a watery milky discharge. Ive been swelling at the feet, cramping, cigarettes are starting to taste nasty, am having a metal taste in my mouth, and my boobs are sore. Stress? Could be the main cause, but could I possibly be pregnant?
