It is one week until my period is due. Ovulated on August 5th or 6th. Today i had brown blood in a very small amount and a little mucous with that. I have had mood swings a little and a craving of no food. Every smell is nauseating to me right now. i have to force myself to eat. I have low back pain. We had intercourse on the 3rd and the 5th. We have not been trying but not preventing and I pretty much just assumed there was a problem because we have been together for 2 years and nothing. Even at one point we did try then it was just not happening. What should I think? I dont think a hpt would tell this soon. I have heard from many women that it is best to wait til u miss period. I just almost feel absolutely positve.
