Hi, I've had 2 kids already and my husband and I have been having unprotected sex but we don't go all the way meaning he pulls out. My question is that I have missed a whole month without my period, and I usually am a couple day off each month but I usually do start. Then I took 4 pregnancy tests and all came back negative. Could I be pregnant or coulld it be just stress. Please help.:confused: thanks.

It could be stress. A cycle in the normal range can be 19 to 35 days. After 35 days, you should call your dr.
