Pregnant after ectopic

Tyna
Is anyone else pregnant after they had an ectopic pregnancy? I had an ectopic from March- june '16 and found out Sept 26 '16 that we are expecting. I had one hcg done and that was the 27th of Sept. Number was 36. My ob wants me to go back on the 11th and get blood done again. I'll be 5+2. I'm hoping baby is in the right spot. Just a little worried.
