Irregular period..

Is there anyway to figure out when you ovulated with irregular periods? So the first fay of my last period was the 8th july lasting until 14th (vvvv light period), according to my app i was due to ovulate on the 16th july. Due on my period again on the 2nd aug but never came on. 39 days late for my period. Had a transvag and saw a tiny bean so still early. Any guesses how far? Scam booked for 10 days. Longest 10 days of my life👶🙄
