I had unprotected sex one time in March after my period had ended. I spotted red on the 31st, pinkish with discharge on the 5th, & 7th or April , and brown on the 9th & 10th. Throughout these days I've. been experiencing weird symptoms such as real bad nausea, breast pain, mild cramps, fatigue, not really been able to eat, and I've gained 15lbs within this one month out of no where. (None of my activities or eating habits has changed)  My period for April was due on the 12th, but it came on the 11th, so I thought everything was okay.. Well this morning it's the 3rd day of my cycle (I only have a 4 day cycle) and I felt like I needed to go pee and when I sat down a blood clot came out with just a little urine. I started cramping and feeling sick a few mins after. Usually the pms symptoms would be gone by now..I never had a blood clot on my period before so can someone please tell me what they think is going on or what I should do? I just need advice.
