Pregnant right after period ?

Octavia

Has anyone had a full period then find out they're pregnant about 10 days later? I had a normal period Nov6th-Nov10th and went to have my annual exam and my OB tested my urine and told me that I am pregnant. Of course I'm super shocked because I tested before my period and it was NEGATIVE. She has me an appointment set for Dec.7th and I am freaking out because I had an ectopic pregnancy this year in Feb w/ my right tube being removed. I'm scared of this happening again. Has this happened to someone and you actually were pregnant and had a successful pregnancy?
