So I have been having some awful mood swings and today I went to take a bite of a sandwich that I wanted at first but the minute I bite into it I felt like throwing it up. I have also had some cramping in the lower right abdominal/ pelvic area and my breasts are becoming tender. I also have had some creamy, white discharge. I feel like I may be pregnant. My last period only lasted 3 days (normally lasts 6) and the blood ranged from light pink to brownish with some stringy mucus? In it.
