my last period was the end of november, and i didn’t have one for the month of december. My period is about 4/5 days late. I currently have the kyleena iud and i’ve had it for 3 months and i’ve been having my periods regularly since then. my boyfriend and i are pretty sexually active. we don’t use condoms, but he usually pulls out. there has been 2 times where he hasn’t pulled out, but i’ve had my period since those times. do you think there is a chance i could be pregnant? even with the iud?
