IUD- no period and two two pregnancies test both said not pregnant

Am a little worried, background. I took my IUD out on the 19 of June, at that time I was on my period, am supposed to start my next period yesterday which was Monday and nothing. I have taken two pregnancy test and both said not pregnant. My breast is is sore like when am due to have my period, but nothing. I had the IUD in for 2 years and it was the 10 years one. Anyone have any experience with this? When I was on the IUD I ovulate, but when I took it out I didn’t experience or see that I was ovulation. Am very confused.
