What should I do now?

I just went through my second miscarriage in four months, last on in April. I do in home care and when I first fell pregnant I was taking extra precautions because I was worried to mc again. The client I was working with wasn’t cleaning out her cat box often enough, and the smell was really bothering me. I cracked the door to her bathroom so her cats can go in and out, but so I didn’t throw up from the smell. Every time I cracked the door the client would ask me to open the door, after I told her about my pregnancy I thought she would be more understanding, but she clearly didn’t give a crap. I quit working with her, and this specific client is very abusive and causes to much conflict, so I decided my baby is more important and I will go work with somebody else. My original supervisor did put me on the schedule after that, so I picked up work with a new supervisor, and everything was fine until I admitted myself into the Er because my water broke, and i had to go into emergency D&C. My phone was dead and I couldn’t call into work, but my supervisor was understanding and I was going to go back to work the following week. The day I’m suppose to go back to work out of no where the new client I was working with for the past month said his medication went missing, and he called APS and they opened a investigation. I haven’t been back to work for a week now. I’m trying to stay calm but it is very frustrating that this guys word can instantly put me out of work, and I’ve even called APS. Of course the case will get dropped and everything however I’m at mercy of the system, and until the process is completed it puts me in a bad situation, even though I didn’t do anything wrong! My supervisor said she is doing everything she can to get me back to work, but apparently it’s up to her supervisor. What do I do in this situation? I’ve offered to take a urine sample, and give them paper work from the hospital and do anything to get back to work and I feel like I’m just pushed to the side. I don’t understand why the client would do this to me, other then the fact I didn’t go into work, and took off three two more days to heal, and my sup just told him I took personal days. Clients can get upset and called APS to put them out of work by lying and it happens, however I never had issues with this client and always got along with him. I texted my supervisor everyday trying to go back to work, and called the APS case worker, and now waiting for my supervisors supervisor to give her the okay, but it’s taking forever, and I don’t think I should have to miss work for something I didn’t do, specially when I’m trying to start a family and have bills to pay. What should I do to get back to work? It is a union job but I’m not even sure if the union would help beyond the actual company.

I’m also going to school as a medical assistant, so my schedule just works better with this job and I get paid pretty decent so I wasn’t working full time during my pregnancy. I really don’t want to just quit and find another job.
