As we all know, the commonest reason for missing a period is pregnancy. This is why, when you miss your period, your first thought is - Am I pregnant ? If you are infertile and have been trying to conceive for some time, there's a lot of hope and suspense when your period does not come on time.
So you check by doing a urine pregnancy test - and keep your fingers crossed - hopefully, this is the time when you've finally hit the jackpot ! Maybe it's the weekend trip you took which finally did the trick ?
However, when you find the test is negative, your hope go crashing to pieces ! Maybe I did the test too early ? Or perhaps I didn't do it right ? Aren't there lots of stories of women who were pregnant but whose pregnancy tests were negative for many weeks ? Maybe the test is not very reliable ?
The reality is that urine pregnancy tests are quite reliable - and if these are negative, this most probably means that you are not pregnant.
Your next step is to do a blood test for HCG to find out if you are pregnant. This is much more reliable. If this is negative, this establishes the fact that you are not pregnant.
This means the reason you missed your periods is because you did not ovulate. This is called anovulation. You may need to induce a period with medicines.
