So I'm almost 22 weeks and I've been sick for a little while. Just found out I have the flu and pneumonia... my job is less than forgiving and couldn't care less about my health or wellbeing. Any tips you ladies have for fighting this? I have been given an antibiotic but .. yet to see results. The fevers are killing me and my heart rate being so high, over 140 is making my little mans heart rate rise too. Luckily that's the only way he's been affected so far. 
This is absolute hell though. 😓
