Does precum contain enough sperm to get you pregnant if you have sex when its present? Also, if the guy pulls out and the cum gets all over your vagina and the a few minutes later he re-enters you, is that a pregnancy risk? My friends have told me that it's impossible, but I don't know. I'm scared, please help!

So this all started a month ago, I had been on my period for five days and I had sex with my boyfriend during my period. Around four days later we had sex again. Then we had it once more a week after. He usually goes in me for like 15-30 seconds without a condom, and then he puts a condom on. We've been thinking that I am pregnant, but instead of going anywhere to get checked, we're just waiting for me to get my period, because he thinks he didn't pre-ejaculate and I didn't know you couldn't feel pre-ejaculation until I read other peoples questions and your answers. We're just so afraid that I might be pregnant. We're both young and not ready for a baby. I AM SO SCARED! I can't even explain I have a bright future ahead of me. Is there a possibility I can be pregnant? I am going to keep waiting for my period its supposed to come next week, but what do I do? I am so afraid to even think about it. PLEASE HELP ME!!!! What are early signs of pregnancy?

Is it possible that some boys just don't pre-ejaculate. I don't believe that my boyfriend ever does. I have checked multiple times to see if there is ever anything on the tip of his penis after he gets an erection and there is never anything there. Also, does pre-ejaculate always contain sperm?

I'm 17 and my boyfriend (16) and I have been dating for 2 years. We have decided to not have intercourse, but we do have manual sex sometimes. The last time we fooled around was about 2 1/2 to 3 weeks ago. I had my period last week, and it was on time, but only red blood for 2 days; then it was pinkish brownish stuff. Today and yesterday I've been peeing nonstop. My boyfriend doesn't think he pre-cums, ever, but I did feel something at the tip of his penis--was it urine maybe? I'm worried that maybe he had pre-cum on his fingers when he touched me (he went in pretty deep) or that I touched myself with it using the bathroom. I'm really worried that I'm pregnant; please help.
