New here! TTC and need some advice!

Kelly • Boymama of 3 💙
Hello all! I'm Kelly, 30 years old and my husband and I are TTC #2.  I recently got off of mirena in January and was put on pill. I stopped taking pill mid March and had an episode of bleeding due to getting off pill. I am unsure when my period starts since I just was bleeding due to getting off pill. What should I do? Still TTC or wait until next period and then start tracking? 
​Thanks loves!
