My menstrual cycle in October only lasted for two days. Then my cycle last month, which was November lasted it's normal length (4-5 days) but was bright red in color. And my first day was the worst regarding cramps. Two days after my cycle went off (which was on a Monday) I woke up vomiting. I didn't feel sick so I went ahead to work. I was at work about 15 minutes until I began vomiting again. Left work and went straight to the Health Dept for a pregnancy test. It came back negative but I had already expected that considering my cycle had just went off. But judging from my previous period it had it's place in my mind. So every since my last menstrual I've had mild cramps, increased appetite, fatigue and crazy emotions 😂 (I've started to cry a lot). I just recently downloaded the app and I entered in my menstrual history and according to my calender I was supposed to expect Aunt Flow on Dec.7th . well her it is the 17th and I haven't had my period still. But I'm cramping like it's about to arrive. Same cramps I've been having since my period went off last November. I'm supposed to get another cycle on the 30th . I haven't tested. I don't wanna jinx myself or get my hopes up . What should I do ?
