Okay, so my partner and I started having unprotected sex August 11th. My fertile window according to the app started August 11th, but my ovulation tests were negative. Well, I was supposed to start my period today. However, on August 28th I got a positive result back on my ovulation test, had egg-white discharge, and the right side of my body was cramping. So, I think I was ovulating the 28th. My question is, when should I expect my period? I just want to know when I should test for pregnancy.
