My doctor told me that it is not good to go over 3 months without a period because of the buildup on your uterus and it could cause more serious problems. I am going on 2 months without a period and my tubes were tied 3 years ago so I'm waiting on blood test results and have an u/s on weds to see if I'm pregnant. She also said that it could be other things (however she says unlikely given my medical history but still testing for them) such as a thyroid issue, pcos (poly-cystic ovary syndrome), or stress.
Whatever the cause, you still should see your doctor right away. Even if your not pregnant, it could be something else that needs immediate attention.
Most certainly go see a doctor, and I hope everything works out let us know.
definitely go see a doctor obviously there is a reason your not having your period and if you are pregnant and for some reason its not showing up on a hpt then you need prenatal care asap as you would already be in your 2nd trimester.
you should definatly see a doctor asap......... because whenever you have any changes in a period, you have to get various things ruled out.....just in case. hope all goes well. and that you are in good health....
