Senior three is under great pressure next semester. I don't know if I will get pregnant. Three summers ago, my parents and I slept in the same bed, and I was afraid I couldn't learn.

Judging from your description, you are definitely not pregnant.

It's normal for you to be stressed next semester, but don't be suspicious. That was three years ago. Of course it won't get you pregnant.

I suggest you put all your energy into your study now and adjust your mentality.
