I remember how overwhelming everything felt when I first got married and had so many doubts. But kissing is just beautiful and harmless, it definitely won't lead to pregnancy.
I am not an expert, but from my own experience, kissing is just a way to show love. Pregnancy only happens through actual intercourse, so you can relax.
Oh god, I remember panicking about the weirdest things when I was younger! Please don't worry, kissing is totally harmless and cannot make you pregnant.
It is totally okay to feel confused and ask these questions when you are anxious. But please don't worry, kissing is completely safe and there is zero chance of getting pregnant from it.
