I think you'll need to go to the doctor because of your history of a tubal pregnancy in the past. That's very serious and as sad as it is that you had to terminate, the alternative is your death. You would be dead if they didn't terminate. Who would take care of your 5 year old if you're dead?
Given that history, you really need to go to the doctor and make sure everything is ok. They don't make those kinds of decisions lightly, they would only propose that as a last resort. You can't not go to get checked out and realistically expect a healthy pregnancy. That's why I suggest you go, and soon, to make sure the baby is in the right place and not in the tube again.
