When can I take a pregnancy test?!??

So according to the tracker my Ovulation date was 1 April. My husband and I had sex on 30 March and he didn’t pull out.

Literally the following day I was having ovulation pains (which I feel each month)

So I’m not exactly sure if I actually ovulated on the 30th/31st or 1 April.

Either way, HOW LONG DO I HAVE TO WAIT TO TAKE A pregnancy test?!?! The suspense is killing me and idk if I can wait another 3 weeks to see if my period comes. 😩
