Ttc after mirena iud

I got ny mirena iud removed December 24th. I had no bleeding the day of or the day after but the second day after i had insanely heavy bleeding and it lasted 2 or 3 days. I also spotted January 7th and it barely continued into the 8th. Hubby and I had sex around the time of ovulation (using opk). What im wondering is did anyone struggle getting pregnant after their iud? Im getting random cramping and glow and my other period tracker says my period is due today and ive not had anything. The cramping isnt bad but i do notice it and im nauseous and overly tired. Do any of you think there is a chance i may be pregnant? Or should i wait to see is AF decides to show up. Is it normal if AF doesnt show but negative tests singe i just got my IUD out??
