When should I test

Hi everyone, I'm looking for some advice, this is my first proper month tracking period and ovulation, I got my period the 19th of April they lasted until the 24th of April.. my app predicts that I started ovulating on the 28th. So my husband and I have been active since the 25th and still going..when should I test? Could anyone tell me.

Thanks in advance 🙂🙂
