What are the odds of being pregnant?

Please no hate comments, I know it’s irresponsible but had unprotected sex Jan 29th, original ovulation prediction was Feb 4th making Jan. 29th a week before. Got stretchy fertile CM Feb.3-4th + I input my bbt. Because of this the app later showed my ovulation date for the 7th. I haven’t been feeling anything out of the ordinary from what I can tell my cervix is hard, I’m dry, have had some mild cramping and breast tenderness which is not uncommon for me before period. Anyone have any insight, am I stressing over nothing??
