Its been 2 years I had my right falipion tube removed since then trying to get pregnant why is it taking so much time?

Will take longer, ge. Avg rate of pregnancy is 10-20 % per month; you will have to ovulate from the same side as the patent tube which is rtouyghly 50-50 so it may take a bit longer, checm a predictor kit and you may need whats called an hsg to ensure the tube still there is oopen; also 40% chance of male factor.
