I thought that I might have been pregnant 2 times. I came on aug 20 and went off on the 26. I had sex 7 times with no condom on the 31st and on sep 4th. On september 5th I came back on my period, however not as heavy. So then I told myself that I would wait and see what happens. Around the october 3 I started seeing light brown then light red and it keept going for nine days. I finally had a period but this one was also rather light. Now I was supposed to come on the 11 and all I got was light brown and pink that one day. It's the 15 and now it is nothing there. Could I be pregnant ... Someone please help me out. I have clinic appt on friday ... But if I dont need to go I wont
