TTC after ectopic but too soon?

CD • Ella born 12-27-16 🌈
I had emergency surgery due to a ruptured tube and internal bleeding on Christmas Day. My tube was completely removed. My doctor said to wait to try again until after one regular period. I bled about a week immediately after surgery but nothing since. My husband and I did the deed last night. I took an ovulation test for the hell of it and it's super positive. Now I'm scared we could have potentially conceived. I'm happy but worried because we weren't trying and the doctor recommended against it. Any one have thoughts at all?
