Me and my husband have been using the withdrawal method. He pulled out but there was possibly cum inside me. We're not preventing pregnancy so if it happens we would be excited.

I've been having nausea, diarrhea, abdominal pain, cramping, back pain, headaches, bloating, and cravings.

We had sex a few day before my period was due. I did get a period but it was only 2 days which is unusual because my periods usually last a week or more.

Does anyone know what this could be? Is this a pregnancy?
