Hello, and I hope i can help you today.
If your pregnancy
test is negative, and you are having a period (even if it is not the typical flow pattern for you) then you do not need to be worried that you are pregnant.
of worrying about getting pregnant can alter the frequency and quality of your cycle, but as long as you have some marker of bleeding at the expected time, you can trust that you did not conceive. In addition, withdrawal is not completely effective as a birth control method, but it does prevent pregnancy about 85 percent of the time.
I hope I was able to adequately answer your question today and that this information was reassuring.
