So I've had my period for over 6 months now, and it's been really great. My only worry is that for a few months my period didn't come for over two months, then for a while it came every month, and now I haven't gotten it in over 40 days. Should I be worried about getting pregnant? My boyfriend and I have sex pretty regularly and we don't use condoms, is it possible to still get pregnant now, even after the IUD has been working all this time?
