Hi, the same thing is happening to me at the moment to and the EXACT same situation! I’m also frightened as to whether I’m pregnant or not so Im not totally sure. But I may be getting a pregnancy test but I’m still unsure. I personally think that there is a chance of being pregnant so I suggest you talk to your parent/s, especially your mother as she would have more experience with pregnancy. (As she has a child; you)
I’ve talked to my mother but she doesn't want me to get a pregnancy test. (Im underaged) So Im also very frightened but precum already has only so much sperm in it and besides it’s already hard enough for regular sperm to fertilise an egg so I think the chances are more low rather than high. But get a pregnancy test after 9-10 days and let me know how it goes!
