I am moody, have extremely sore breast, I am tired all the time, and even nauseous at times. My period arrived on time, but lasted longer than usual, I took 2 pregnancy test both negative. Could I be pregnant?

If you had a period and have negative tests then you're not pregnant. It sounds like your mind it playing tricks on you. Sorry :(

It's unlikely. Although some women do experience what they think is a period during pregnancy, that bleeding is usually lighter and doesn't last as long.

You could be pregnant, and there's really no way for us to tell for sure, but I would say that you aren't, based on what you posted here.

By all means test again if you're not sure, but I'd wait until your next period is due. If you get that period, then you're most likely not pregnant. If not, test again using first morning urine, or see your doctor for a more accurate blood test.

Good luck.
