I would call soon and get your platelets checked. Maybe even go into an urgent care or something. I had a scare last year when not pregnant- I woke up with bruises all over my arms and legs and went to urgent care. My platelets were dangerously low- 15,000 when they should be over 150,000. It is called in many cases ITP. Hopefully it's nothing but it's not something you want to mess with . If you do have very low platelets and you cut yourself you could lose too much blood. Evidently it is more likely to happen during pregnancy too b/c your body is in a hyper-immune state. Good luck- again hopefully it's nothing but it's worth checking out.
