Can I not take the glucose test??

Okay so I’m only about 6 weeks with my second. With my first I took the test at 28 weeks and it made me so sick I was dizzy and tired all day after it. Then I failed. So I went back and did 3 hours and was even sicker. I could barely get up to get my blood drawn without the lady walking me because I was so dizzy and sick with the worst headache. I failed that one so yeah I had gestational diabetes. Well right after I had my baby I was supposed to go back at 6 weeks to get another one done pp and I called letting them know I had a cold and since covid was just starting they said don’t come. Well I forgot about it and never did it. I’m 10 months pp and 6 weeks pregnant again. I know there going to want to do one early this time. Is there another way of finding out ? My dr didn’t give me any other options last time but I’m hoping if I tell them how sick and tired I was (literally felt like I was going to faint) that they will let me find out a different way without drinking that.
