I don't think it will affect conceiving but pregnant maybe will affect. My wife has gastric and hence always take food on time, only occasion maybe due to stress the gastric will attack. When she got pregnant, we taught she is gastric because her body got a lot of wind and always burb and worst she feel pain when press, hence the normal doctor gastric medicine cant cure. Hence, she admitted to hospital for gastro consultancy for check up and has to take controlled medicine to reduce the wind that cause pain. That time i only know my wife is pregnant. Supposingly the gastro doctor want to do "endoscopy" to see internal stomach, liver for any bacteria or ulcer. Since pregnant, she cant opt for that. I feel appreciated for the doctor proffesionallity which he suspect something and transfer my wife for gynae and further check up

Also i suggest you go do the blood test for "helicobacter pylori".

Just sharing my story and hope it help you for preparation.
