when do you stop ???

so I found out I was pregnant last week. got blood work done level was 8.6 very low so prayed and prayed for a sticky baby and two days later started cramping and spotting. went in and level was 3. the next day I miscarried. my wife and I still wanna baby very much but I had a 24 weeker who passed away in July 2016 and then a chemical pregnancy and now this miscarriage. what would be ur advice? we are so on fence right now to stop or to try again. feel like my body is completely against me at this point.
