what is happening??

Sierra
I got my IUD taken out April 12...so we have been trying to conceive since then. Had my period a week later for 5 days. And then nothing....period is now a months late. Plus super weird body changes. Lots of nausea and cramping. Constantly going to the bathroom bc I feel like I'm gonna start my period but then...nothing. Also, negative urine tests and negative blood tests.
Anyone have anything similar happen? I'm at such a loss. And worried I won't ovulate if my period doesn't come 😱
