Help ! Yeast infection & Monistat 🔥 😫

So I’m 17 weeks pregnant and just used monistat for a yeast infection because it is on my list of “okay” medications to take from my doctor . It now feels like it is burning more than it was before. Is this the medication just working or am I having an allergic reaction or something ?? Anyone else have this problem ? Don’t know if it’s going to effect the baby or if I should rinse it out or let it do it’s thing... Help!
