First month off birth control

Was supposed to get my period yesterday but since this is my first month off the pill I was expecting it to be late.  Had sex on the 26th when I was ovulating and took a test yesterday, it was negative. Had sex yesterday and it was a little bloody after but no signs of AF at all today.  This is all pretty new to me. If I don't get my period in the next couple days when should I take another test?  We aren't necessarily TTC but we aren't not trying. I'm off the pill and we want babies. We just don't want to stress about it. If it happens it happens. You know?
