Simple answer, no. Swallowing does not cause pregnancy, it has nothing to do with the digestive system. Pregnancy needs sperm to reach the egg directly. You can relax about this one.
Lot of girls get confused about this, I did too when younger. It cant cause pregnancy, the stomach and the reproductive system are totally separate. Good that you asked instead of worrying silently.
I had similar doubts when I was new to all this and felt shy to ask anyone. The answer is no, it doesnt lead to pregnancy. Theres nothing wrong in asking, better to know correctly na.
No, it cannot. Pregnancy only happens when sperm meets the egg in the reproductive tract. Anything swallowed just goes to the stomach and gets digested, theres no path from there to the uterus. So no worry on that count.
