We keep fighting and I'm pregnant!

I'm almost 5 weeks pregnant and My husband and I have been fighting since yestersays doctors visit. The doctor was an incompetent idiot who made me do a urine test knowing I just chugged 4 glasses of water. He then said he didn't know if it would dilute the pregnancy test. Well of course it would dilute the pregnancy hormones and be a false negative! Low and behold, it came as a negative test! I was so distraught and i challenged him by asking some direct questions about the test. He said he didn't know. 
My husband was there and kept scoffing at me and was embarrassed I was upset and being curt with the doctor. Mind you, I was just told erroneously that I was not pregnant. Of course I was upset!! Instead of being supportive by giving me positive affirmations or just anyhing, he took the doctors side and acted like it was me being out of line! 
 Anyway, I was not supported by my husband and now we have been arguing constantly. Slept in different room.. Yelling.. Etc...  I'm stressed and don't want to miscarry Bc I'm so stressed. My husband is more concerned with being right than not fighting. What do I do? I am angry with him and don't want anything to do with him. Who gives a shit about being liked by an incompetent doctor when it's in regards to the health of my baby. Of course, I took more pregnancy tests this morning and all were positive. Never seeing that incompetent doctor again.
