Did I conceive?

Hello, my partner and I have been trying to conceive our first child this month. A lot of apps say I ovulated between the 29th, 30th, and 31st. My LMP was on the 17th. We DTD on the 25th. Is it possible that I could have conceived, given this time line. I felt a severe cramping pain and watery CM on the 29th, and just water mucus on the 30th. Help please.
