So I am 21 and my periods have been usually regular, sometimes comes a couple days earlier sometimes not. However, this month I am having me period twice. The first couple days of my previous period were heavy and then nothing which I usually have it for 5 days. At this time I was stressed out a lot, I tend to worry a lot. Fast forward two weeks later I'm on my period again. I did have sex near my ovulation date but it was protected. 3 days after I ovulated I started. It's been heavy and bright red, then at night there isn't much. My breasts are kind of sore but they usually get like that when I'm about to start a period. No cramping this period though and I'm supposed to start next week. I do feel like I've been under some stress, and I had taken sinus medicine syrup for my sinuses so maybe that did something, and I have started drinking a tiny bit more. My diet is bad, I'm a smaller girl for my age do I eat whatever I want. This sucks I don't know what this could be, but I'm going on a little trip in 2 weeks and I don't want to freak out about if I'm going to start bleeding or not. I'm waiting for this period to be over do I can visit the Gyno. Is this really normal or what? This sure does suck, and this is the first time I've ever been like this.
