Sick and pregnant?

Sore throat, completely congested, body aches a little. I can’t miss work because I only have 3 “sick days” before I get fired since I’m a new hire and I have to use those days for midwife appointments. They don’t allow any doctors notes or hospital notes to excuse you within your first 120 days. Asked my boyfriend if I should stay home but he’s been very cold and unhelpful. He said “do what you want but you don’t have many days to use before you get fired”. I just need tips to help me get through the day.
