Every state has free clinics, so I'm sure you'd have to cheek into that. Also my doctor has said that when you have and IUD they ususally take your period away compleatly, also they say that you won't be able to feel your strings after a while because they actually cut them pretty sure and they get pressed up around your cervex. And possibly you're not reaching far enough in to feel them. Tho I wouldn't worry about it because the chances of you being pregnant are slim because the coper IUD basically blocks your uterus so that a ferilized egg can't inplant. Any who.... my best advice would be to go to a free clinc because they would be able to give you more infromation about what is going on. I hope this helps a little bit... good luck!
Yea I keep having the same problems too and I have even gotten a blood test done that came back negative. One woman said that she had to get an ultrasound done to find out that she was 9 weeks pregnant but had lost the baby and also had kidney stones. I'm scared that I could be pregnant too and I have no insurance anymore do you have any idea what I can do about that?
