I had a 5 year iud in for 8 years

So it was expired so I took it out my self because the dr who put it in wanted  250. To remove it and public health wouldn't cause they didn't put in. So I didn't bleed for 8 years , after I removed it I started my periods agains, now I got the iud because I can get pregnant using some dudes toothbrush. No not really but easy as hell. Now I've been trying since I pulled it out. Does anyone know if they screw Ya up. Does it take a while to get back into the swing of things. Somebody says once they come out your more fertile, does anyone know anything that would help me,?
