Late period but negative tests
Hi! I have been trying to conceive since around December, and have had my IUD removed since November. My periods have not been regular down to the day, however I have started my period between the 28-31st of each month since being off of birth control. I did not start my period at all in April. My last period started March 30 and ended on April 3rd. I’m only a few days late based on the time frame that my periods would normally start, however my tests keep coming back negative. What should be my next steps? Has anyone ever experienced this? Thanks for any help in advance!
