Lovenox once or twice a day?

So I’m about 4-5 weeks pregnant now and started on Lovenox injections be day I got the positive. I was diagnosed with Antiphospholipid Syndrome (APS) after two consecutive miscarriages. I’m trying to do everything right this time so that everything goes fine and am naturally very nervous. My last miscarriage was in April and before that I had one in December. My hematologist put me on Lovenox 40mg twice a day so I’ve been doing them but now today the nurse there called me and told me to only take it once a day. So now I’m confused as to why they changed it. I told them I’m fine with twice a day if it’s going to prevent another loss and he said it’s a prophylactic dose and I only need 40mg once a day. He also said I don’t need to get blood work to check my levels to make sure it’s working. I guess I’m just anxious and want to make sure the medicine is working and my baby is going o be ok. So for those on Lovenox have you taken it once or twice a day??
