So about a month and a half ago I had my period at the end of June. Gave one of my friends a hand job and he ejaculated on himself and my hand. I made sure none got on my legs or pants (made sure to wear a tampon to) we wiped everything off and then I waited a couple hours before showering and everything. Next I went to boot camp at this end of June and that brings on a lot of symptoms of missed period. I was supposed to have my period at the end of July but it never came. I spotted for a couple days but that's it. I waited for a couple weeks before I noticed weight gain and the bottom of my stomach to get larger and I have gained weight. Took a pregnancy test the other day and it came out negative. Making am appointment with my doctor on Monday but I'm just wondering if I can be pregnant without any of the signs except a missed period.
