Yeast Infections 😕😕

Ive only had yeast infections when I was pregnant almost 2 years ago 🙄 they were constantly but my on was usually the one to detect them since I didn’t experience any itching or burning. She always said she saw it in my urine anyway.. I think I have one so I went and got Monistat 7 I put it in about 15 mins ago & I have this terrible burning sensation and like an urge to poop sorry for the tmi but can I pee or am I supposed to hold it all night? Also the itching is getting terrible I feel it burning ☹️☹️ please tell me this is normal? & what I can possibly do to help the itching and burning sensation
