Hi, thanks for using healthcare magic
PCOS is one of the most common causes of irregular periods
. Treatment normally involves (1) weight loss
(if there is excess weight), (2)the use of metformin
which decreases the insulin resistance
associated with the condition , aids in weight loss and improves fertility (3) the use of medication to help with ovulation in women who are trying to conceive (clomid) or the use of birth control in women who are not (4) if the clomid does not work to induce ovulation then there are other medications available
Unfortunately, if 3 urine and 1 blood test
are all negative for pregnancy, it is unlikely that you are pregnant. Even if the urine tests were falsely negative, the blood test is unlikely to give a false result.
If you are trying to conceive, you may want to consider treatment for the PCOS as mentioned above.
i hope this helps
