I been with my boyfriend for five years didn't get pregnant yet we never use protection

5 years is actually a long time but yet its still not uncommon, I've known people to try 10 years and then suddenly it happens! But I can understand how frustrated you both might be, have you both been checked out to make sure every thing is in working order? If not it would be nesscessary giving how long you've been trying.

Have you been able to have sex on a regular and frequent basis each month in the last five years? If so, I agree with addy... five years is much too long to be trying without success.

Are you having sex only at certain times or throughout each cycle? Are both of you in good health? Any passed health concerns? Is extreme weight a concern? Have both of you done the basics of making lifestyle changes that you know would be healthy and wise? Avoiding cigarette smoke, drugs, etc.. What are your ages?

Definitely time for both of you to be checked out if you haven't done so already. If you have, what tests were done and what were the results?
