TRYING AFTER FIRST LOSS

Im almost 3months postpartum,my baby died just 4days after birth and i couldnt breastfeed.so i was trying to conceive again and my period started very soon after 6weeks postpartum April 29th! so its june 1st here where I live,and ive had sex almost everyday. i even tested my blood hcg 2weeks before my periods due and it came negative so it may be that i ovulated late! should i test tomorrow or after a week? i want a baby really bad after losing my child.
