Possible APS diagnosis after stillbirth

Hi, I am hoping for feedback. I found out at 35 weeks my baby had no heartbeat, I delivered him the next day. We are heartbroken and trying to find our way. I had “suspicious levels” indicating APS, just waiting for the weeks to pass for additional testing. We are also waiting on placenta pathology report. I have so many questions...plus want to be prepared when speaking to my doctor.

What were your levels when you found out you had APS?

Has anyone had a stillbirth that APS was found as the cause? Have you had a successful subsequent pregnancy since?

Has anyone been told that APS is a cause for infertility? (It took 3 years to get pregnant, we conceived with our first IUI)

Do you have another autoimmune with APS? If so, which one?

Thanks in advance.. I’m just searching for answers
