Hello dear I understand your concern If you have normal menstruation, normal maturation and rupture of follicle, patent fallopian tube and normal semen parameter of partner then definitely you will become pregnant. Cycling for one hour does not cause any problem in getting pregnant. You can also do running, swimming, skipping, walking, yoga. But avoid excessive exercise that cause any type of injury Do daily exercise for 45-60 minutes in morning Take small frequent meal rather than large meal Avoid: excessive sweet, fatty/oily/spicy food, alcohol, smoking Eat healthy diet and drink plenty of water Hope this may help you Contact further if follow up needed Best regards Dr. Sagar
