So I am 15 days late for my period and I've taken 2 pregnancy tests both negative. I am never more than 2 days late and I track my period through an iPhone app. I am always on target. My boyfriend had a clip in vasectomy 3yrs ago just after his 2nd child was born. Is there any way I could still get pregnant ?

It's possible for a vasectomy to naturally be reversed. However, they are considered to be permanent as the failure rate is quite low.

There are a number of possible reasons for a period to be late or be skipped altogether. Sometimes no reason at all is determined.

You have a few options.

*You could just give it some more time and see if your period is late for this month. If still no period, try another pregnancy test, making sure you follow the directions exactly.
*If still no period, and negative test result, you could wait and see what happens when you would expect your period for next month. Test again at that time if need be.
*You could see your doctor and ask about having a blood test done.
*You could have your boyfriend see the doctor to have a semen analysis done to determine whether there has been a reconnection. This would give both of you some peace of mind as well.

And of course, sorry to think it, the boyfriend is lying and did not have it done. I have heard of men lying because they did not want to use protection.
