garments colored with pink for the wedding

So I had my Paraguard IUD removed on October 5th. I have been super nauseous since 2 weeks before I had it removed. I also have to pee a lot. I am on the pill and have been since the Sunday after it was removed. Now according to my pill pack I was supposed to start my period yesterday. Still no period today. I took a pregnancy test today and it was negitive. Anyone know if I may still be pregnant or if it's just my body getting used to my pill pack? garments colored with pink for the wedding
