Hi. My husband and I decided I needed to remove my IUD for a while so I can stop having BV infections and yeast infections. I am currently using metro gel intervaginally. While giving my husband a hand job, he came on the inside of my leg and when I went to get up, cm got on the outside of my vagina. I wiped with a towel and took a shower where I washed with antibacterial soap. Is there a chance I could get pregnant? Should I use Plan B?
