I just got on the iud about 2 1/2 weeks ago and I was told to wait a week before having unprotected sex so I took a plan b. I know it’s stupid but I didn’t want to go through getting an iud and becoming pregnant right away from not waiting. I know a plan b is suppose to make your periods longer and an iud is suppose to make you have spotting but I use a menstrual cup and the blood amount is the same as when I’m on my period and it’s been 2 weeks of this. What should I do?!
