thanks for using health care magic
Cases of tubal ligation
failures have been reported thus
the first thing to do will be getting a pregnancy
If it comes out positive, then a pelvic ultrasound
will be very
imperative to locate the position of the pregnancy.
If the pregnancy test comes out negative, that will be good
and other possibilities would have to be investigated.
It is normal in certain periods to have reduced blood flow and it becomes
a problem when it is repeated.
So, go for pregnancy test and stick with your doctor for follow up.
