Welcome Dtrisha - hope you have success soon! So sorry to hear about your ectopic. It's never an easy experience to have to go through. Hope you are doing alright.
Mod can answer your question better, I'm sure. However, you have to be ovulating at least somewhat since you got pregnant relatively easily. So that's probably not a big issue for you personally (though it's always possible). I know it's super hard not to worry about everything though. I just went through all my tests and several easy Cycle Day 3 blood tests can tell you a lot about ovulation or a Day 21 blood test (if needed). If you are worried you could always ask your doctor. I think they are more likely to prescribe Clomid if you have one tube, because it can force you to ovulate from both sides, making it more likely you'll ovulate from your good side.
If you still have two tubes (though it's always possible there is blockage in them somehow that led to the ectopic), they might want to do a few tests before prescribing. Every doctor is different.
Don't be afraid to ask anything. That's one thing I learned after my ectopic. Ask. Ask. Ask. Get a second opinion if needed. And then repeat.
