Hello, I Had My Mirena Removed 6 Weeks Ago. 2

Hello, i had my mirena removed 6 weeks ago. 2 days after the removal, i got, what i thought was a normal period. Since then, it has been 5 weeks and 4 days and i still havent gotten a period. My husband and I are actively trying to conceive so i thought with all my symptoms that i could possibly be pregnant. I have take 5, yes 5 pregnancy tests and they have all come back negative.
