Ectopic? Someone please ease my mind?


I have been to the dr once at 5 weeks. No ultra sound but i was worried because i have had a pressure feeling on the right sode of my pelvis. Doc said its possible that its just the side baby came out of and theres a cyst there. Well it went away for awhile except when i lay down. Im 6 weeks 4 days today and since yestersay the pressure has been a little worse and its ONLY on the right side. It had started to shoot down my inner thigh. He did my blood work my forst visit and they have no concerns from that. I have not spotted at all my entire pregnancy and this is my 3rd baby. I have my first ultrasound this friday, but im so worried. I have had major anxiety about it since yesterday. Anyone else have this type of pressure feeling? I just need to ease my mind until friday i suppose.
