ANYONE HELP? SPERMICIDE HELP

My vagina smelled like light fishy and a little musky...

I have VERY sensitive skin.

I missed 3 of my birth control pills so I spent the $20 on spermicide.

I used it 2 days ago.

And I just tried it out again.

It combines the sperm and spermicide into a mucus blob.

My vagina itches a couple minutes after he comes in me.

It literally have to either ignore it or stick my finger in there and itch my vagina somehow.

It doesn't burn too bad, just itches like 1/4 sandpaper and 3/4 feather.

I had a weird smelling vagina today and I guess I'll see what it is like tomorrow.

Could spermicide give me a yeast infection in 2 days?

My vagina usually never smells. I cannot make it to the doctor's right now because I am switching jobs. I bought Equate vaginal wipes for after sex to wipe off lube and Summer's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> vaginal wash for PH balance.

Any advice is appreciated. Thank you!
