Pregnancy pimples all over my neck shoulders and sides of my body!!

I broke out with pimples probably the 4th month of pregnancy it's been 3 months and they still haven't gone away!!! I'm pregnant with twins, live in Hawaii and I'm so embarrassed to go swimming in a bathing suit. Has anyone else experienced this? 
Doctor says it's just hormones and it'll clear up on its own or after when the girls come  😑😐😳
