Do I really want to find out?

Okay going on a week now of "morning sickness" sore nipples, heavy feeling in my stomach and fatigue..thing is I did nothing to prevent pregnancy with my ex husband of 10 years and never had any luck nor did he have any kids, I am now with an amazing man who actually has kids..3 boys. I was always irregular for years and years due to depo, but over the past 3 years i have been regular and consistent..i missed my period last month, then BAM all these symptoms follow..I juat dont want to get my hopes up again for a let down..ugh what to do
