swapped from anal to vaginal sex while pregnant & scared ive caused harm!

long story short i made a stupid mistake of trying anal and then we switched to normal sex.

this was last week, and all week my vagina has been sore & sensitive. when i wipe it hurts & feels like it burns (dont burn when i pee), around & in my vaginal entrance feels slightly puffy and burns & so does my labia. ik its normal to have increased discharge but feels like im not fresh and has a slight odor.

have i got a yeast or bacterial infection? and if so can it harm the baby?!

I CANT go to a doctor as i have been put in tempory housing and my old drs have moved me and i have not yet been registered with a new one and i have no way of getting to anywhere else as i have been put here on my own
