how soon did you show symptoms?

Had period roughly two weeks ago, but had unprotected sex shortly afterwards. Hubby has been making comments that he thinks I'm showing symptoms-but I think it would be way too early. 🤔
I'm not a very emotional person, but I've been crying at least once a day for the last four. (As opposed to a few times a year for appropriate reasons.) No real explanation on my part as to why.
