I have a problem + tmi

I am 21 weeks okay ... I have was told a couple weeks ago I had a yeast infection and bacteria vaginitis I took all the meds for the yeast infection but the other infection is still here because I can't keep the pills down ... They are extremely hard to take to start and after 30 mins I throw them up and have extremely painful stomach cramps... I am constantly leaking white creamy discharge and it hurts to wipe when I pee ... What do I do???
