It depends on when you took those two pregnancy tests? Where they at least two weeks after you had sex? And I think it’s a really good idea to take a new pregnancy test.

But, even if it says negative, you should still see your doctor. Several missed periods in a row might be a sign of certain medical conditions. Or it could just be irregular periods. But the only way you are going to find out for sure what’s going on is to speak to your doctor. Three missed periods in a row is not something to ignore whether you are sexually active or not.
