When to test??

I got off my period on the 14th and my d.h and I have been bd everyday since... Would April 1st be okay to take a pregnancy test? My periods are pretty irregular, so can't really wait until my missed period or the day of as I don't know when it is for sure. And I don't know when exactly I ovulated. Also 4 months ago my period was on the 24th.. I had a miscarriage, then it was on the 5th, than the 7th and this month it was the 8th. So when would be good to test? :)
