Hey Brandyjune, I'm a nurse who is going to have mine in December also. Clots are tricky things, first off, let me tell you about prevention. As soon as you can, get up and start moving, pump your legs when you are in bed, wear the SC (sequental compression) hose they give you or the SCD's (a device that wrap around your lower legs and fill and release inflated air to help to keep your circulation good) they give you as much as possible when in bed. Most clots come from your blood pooling somewhere, from decreased circualtion, and movement.
Some can come from surgical sites. Sometimes you can feel a warmth, or pain/ache in your legs where a clot has lodged, shortness of breath, and extreem anxiety that something is wrong due to alterations in blood pressure, breathing and heart rate can also be a sign, but the unfortunate side is that sometimes when throwing a clot, no warning signs are given. This is not to scare you, but it's just the truth. Your doctor will most likely have you on lovenox, a blood thinner, that will help to prevent clotting. I'm sure you will be fine, think positive thoughts, and get this part of your life behind you. You got this!
