My boobs hurt.. bad and I ve been pooting a lot. Feel like I did when I was pregnant with my daughter. I have an iud for 18 months now. Could I be pregnant?

Yes, you could.

Im currently 9 weeks pregnant, and had an IUD in for 2 years, last week they removed it and it was perfectly in place! So YES you can, its rare, but believe me I'm proof =( good luck, and take a pregnancy test asap =)
