Copper Iud removal cycle problems??

Tammy
Hello everyone. Might be too early to be concerned but I wanted to see if anyone else had any problems. I had the paraguard in for 5 yrs. Just removed mid April and I'm waiting for my first period to start. It was removed during ovulation and my period has always been 28 days like clockwork. I'm 3 days late today done 2 tests n both BFN. I'm hoping the IUD hasn't messed up my cycle that's why I went w the non hormonal one. Anyone else have problems. Again I might be over thinking n my cycle might still start. Just hope it's not messed up too much or it'll be hard to TTC. Thanks.
