First, I've never had sex. The only "scare" I've had was that I touched a penis for about 1 minute that might have had a little pre-cum and two hours later had that hand in the vagina (which happened last month). I also once touched sperm, washed my hands, and two hours later went to the bathroom and my hand touched the vagina. Can I get pregnant from either of those things?
Second, yesterday I felt a bit of cramping, so I put in a tampon in case my period started. I got home and pulled it out, and there was a little blood on it. So I put one in when I went to bed, woke up this morning and took it out, and it's almost completely white. My period is due around the 16th-20th of the month, and it's only the 11th. I had my period the 17th-21st of August (after the time I touched actual sperm and went to the bathroom). What could explain this spotting?
Third, I've been feeling nauseous for the past week. There's a cold going around the school, but it's the kind of queasy feeling that doesn't really go away a lot and comes back randomly. I'm 17 years old, in high school, sleeping enough, eating all right...So. Do you think I just might have caught that cold, or is it probably something else?
I don't have the means to get a pregnancy test at this time, so I would love for an opinion. Thank you!
