Stressing out

So I need help 😔 , I was on the mirena for only 1 or 2months can’t really remember but I know for sure it wasn’t more then 2months . I got off the mirena March 13 I started bleeding March 15th for 4 days it felt like my period . So now me and my hubby is trying to conceived and I thought since I was bleeding for 4 days that had to be my period I was ovulating the end of March and made sure I had sex . Now the glow app says I’m a day late & I took a pregnancy test this morning & both were negative I’m afraid something is wrong , Has anymore else been through this ? 😔
