Hi there,

I have been on the contraceptive injection Petogen for two months continuously with no breaks, and experienced very irregular periods. I switched over to Triphasil 28 and have taken them consistently (with no more than two hour deviations from the times I've alloted for taking my tablet each day). I have reached the end of the red tablet phase and had no period, is this normal and should I take a pregnancy test to be sure?

Thank you
