Ladies

So I am two day late & my Af either comes that same day I suppose to get it but late at night or I wake up with it the next day and as now I have nothing just normal discharge I had sex with my so yesterday told him to stop thinking I got it since I was sooo wet but nope I have really tender nipples if I touch them they hurt not so much my boobs just my nipples keep getting this small cramps I am not sure if I should test today or wait till the of the week ? And I wouldn't be surprised if I was pregnant I way to much sex last month my fiancé and I will. Be happy but what do yall think when should I test ? Thankyou
