Hey I’m trying to add my new pregnancy but this darn app won’t let me do it. I tried changing my status from healing from a loss to pregnant but it won’t let me. Then I tried adding a new pregnancy and it just keeps saying there’s a previous due date interfering with this one but the only due date that’s in her is my due date for this pregnancy please help me
