So I've been on the pill for many years now as had extremely heavy periods. They made it lighter but still relatively heavy compared to average.
I use the pill as contraceptive as highly allergic to all condoms so partner usually pulls out as well just to be safe. Long term partner so no chance or any stis.
This month my period came a day late and while not that light it's relatively light for me. Took a pregnancy test just in case and came back negative.
Still freaking out though. I can't seem to calm myself
Please try to be reassured the chances that you are pregnant I you are on the pill and have a negative pregnancy test is really low. If you wanted to reassure yourself you could do another test in a week (though it wouldn't really be needed but might reassure you )
