IUD removal periods

Hi, I never had my period while I had my IUD Marina in. I had it in for almost 4 years. Before iud it was very regular, came either the 20th or 21st of every month would only last like 3-4 days. No cramping, bloating. Only would get one huge zit before hand. I got my iud removed January 24th, I still have not had a period. This app and others are saying today.. but still haven’t gotten anything. Has anyone else experienced this before? How long did you get your periods on track? We’re trying to convince. I did ovulate this month!
