Last month my first period was in the beginning of the month then three days before the second one on the 26th I felt like vomiting because of the smell of the food & had diarrhea as well then the diarrhea stopped but the feeling of vomiting carried on then after three days my second period started but wasn't heavy like the normal period. A few days after my second period I then started experiencing pregnancy symptoms like the soreness of the breasts, nausea, feeling tired all the time, food cravings metallic taste in my mouth, headaches back Pains,lower abdominal Pains, a lot of gas & being moody but when I took a home pregnancy test two weeks ago it said negative. So I'm not really sure if I'm pregnant or not plus I'm not sure when I ovulate.
