Morning sickness and Work.

Ok. I have a dilemma.. I started a new job back in October 2017. I found out I was pregnant in December of 2017. I got bronchitis really bad in the beginning of January 2018, so I had to miss a lot of work. Then by the end of January it turns out I had a miscarriage. Following the miscarriage I had to miss a lot of work. Both these time I had a doctors note. Then late into February I ended up having to have my gallbladder removed due to gallstones. Missed more work but excused. Now comes May I find out I’m pregnant again. Yay! 2018 had been a rough start for me. Now there is sunshine back in my life. I am now 11weeks pregnant but have been having the worst morning sickness that continues all day. The doctor wanted to give me medication for the nauseous and vomiting but I just want to though it out due to being highly paranoid about having another miscarriage. Anyways so due to this I have been missing a lot of work once again. But this time it’s not excused. I can’t go to the ER and get a doctor note everytime I’m vomiting and have to call out.. my copay is $235 every time smdh. I live in Southern California and was wondering if they could possibly fire me over this??? And it be justified.. thoughts and advice would be great right now cuz among puking my brains out I am highly worried about losing my job. Thanks in advance!
