Crazy Pregnancy Thoughts...

So most pregnant people worry about birth defects or health issues but I never worried about any of with Aidan and so far have not with this pregnancy either. But for some odd reason I have this erratic fear that I am going to have twins. I am not sure why because twins do not run in my family and I do not think they do in Robert's either, and I'm young and did not have any fertility so it is not likely that I would have twins but I am so scared that I will! Last night I was laying there trying to go to sleep and I was thinking about being pregnant with twins and not being able to sleep at night because they were having crazy ninja fights in my stomach. Wow I am weird. I need to get in for my ultrasound to reassure myself that there is only one baby in there!!!
