Well where do i start i am 22 yrs old and engaged. My fiance and i have unprotected sex and last monthe my period acted funny I was vomitting and nasueas tired and very irritable. This month I got my period for 3 days Wierd because my usual cycle is 7 heavy days. The first day it was extremely heavy the 2nd was extremely light almost non existant. And the third I didnt even have to where a tapon it wasnt even enough to come onto a panty liner. I am nervous because i am not sure if this is a miscarriage or i am actually pregnant. I also have been feeling a weird bubbly fluttering feeling in my stomach, I do not sleep well at night it is like the fluttery feeling gets stronger. I have not taken a pregnancy test yet. But i have felt like this before and the doctors told me it was nothing. Please someone if you could help I would really appreciate it.
