If that is your concern also, there are signs that could indicate you have a clot somewhere along the vein (typically clots
will be behind the knee in leg veins
). If you notice your affected leg is red, swollen and tender then I would definitely call the doctor.
I have an appointment tomorrow and plan on mentioning my vein issue, but I am pretty sure its just what it looks like, a wonderful varicose vein. I never got them with my other pregnancies so this is new territory for me.
