I don't know what to do...

Tara • Have two beautiful children
23 weeks pregnant and I have been dealing with a miserable stomach virus. Had it for two days and went to the hospital and I felt better. Now the next day, it is back. Same symptoms and everything. I've missed two days of college already and I feel like such crap for missing again. Me and my toddler both have gotten it twice back and forth and I don't know if I should goto the hospital again or what. Can't keep anything down at all and I also can't take my bladder infection antibiotic so I don't know what to do...
