I STOPPED having my period a week ago. It was completely normal besides being almost a week late. I'm not on any form of birth control. Yesterday I started spotting that's only noticable when I use the bathroom and I was very nauseous last night. This morning I woke up, still spotting, and very nauseous. About 10 minutes after I ate breakfast I threw up. I feel completely fine except for the nausea. I last had sex almost a month ago before my husband was deployed... but I had my period. Could I possibly be pregnant? Thanks.
