Sonohistogram and egg count

So my husband and I have been ttc for about two years ago there months ago we finally started going to a fertility doctor and started the tests and exams. Today I had my sonohistogram CD7 on CD3 they counted my prenatal eggs growing? Not sure if that's right terminology but it's how I understood it. Well today I asked (because they did the same count again) what is the normal average combined potential egg growth, she told me 12. Well here's where I get scared on CD3 there were 3 on the left and 4 on the right today CD7 there is only 2 on left and 3 on right. I get my results and "plan" on Wednesday but I'm petrified I can't have my own baby. Has any one else has the same count and successfully conceived?
