Mirena removal- pregnant? Help!!

Candy

I removed my mirena on 3/25. That same week after removal i could tell i was ovulating because of my discharge. I didnt have ANY bleeding whatsoever after. Till this day, no bleeding! I have however been experiencing cramping, fatigue and food cravings. The day before I had the mirena removed my husband and I had sex. We have been having sex pretty much every day since. I took a pregnancy test today and it was negative.

Could I be preggo and its too early for test to come back positive?

How common is it to have these symptoms and no period/bleeding after mirena removal?
