TTC after IUD removal

Hi ladies! I had an IUD (Mirena) for the past 7 years (1st one for 5 years, 2nd for 2) with no AF at all during that time. We decided to start trying for baby #3 and I had it removed 9/19. I still haven't had a period and have been having serious mood swings and light cramping this week. Just wondering how long it took you to get AF after removal and how long to get pregnant. I keep wanting to take pregnancy tests but wonder if it's too soon!
