Af gone an done with

Tiffany • My name is Tiffany and my partner name is Jeremy. I`m 24 he 29. We are trying for baby #1 since June 1, 2014
Ok so AF came an gone everything was normal 4 days it's been 3 days since my last day. Today I've been cramping on my left lower area. After I eat I feel like throwing up (I don't) an some smells are making me sick I don't want to be the crazy girl peeing on a stick 3 days after my period. As I hate seeing BFN anyways!!! What should I do?
​P. S. I also had brown/ pinkish when I wide today.
