Last month on the 9th I had "protected" sex (trojan enz spermisidal), but my partner ejaculated and keep going for a few seconds. I feared that some may have leaked out. My period came on a week later on the 16th. Then it came on again this month like on the 10th. When I wiped it was red as usual, then I put on a tampon for the first time in a while because I just been using pads. When i took it out it was pinkish,brown, red, then the rest of the day and week it was dark red and I filled my entire pad as usual. Could I be pregnant, my lower stomach has been a little tender since during last week, i don't feel sick, but my stomach is looking bloated; i took a laxative thinking i had a blockage because I usually have that problem being constipated, but I've been fine until last week. I haven't had sex since the 9th of last month. Or is it my period about to come on again. I had my period twice, and since it was stated that sperm can live up to seven days. My period did come on last month and this month. So is it possible? Im just waiting for next month.What do you think because I am worried.
