Pregnancy Info HOME

I was Ovulating on the 21st of Aug. I had unprotected s_x with my boyfriend. I also had around 4 or 5 acts of unprotected s_x after that. The last time was last Tuesday the 4th of Sept. I was due for my period on the 6th. I started cramping on the 7th. I had started to bleed but very much lighter than my normal period, but also it is not spots, its a little more than that. I took a pregnancy test on the 7th of Sept. and today the 10th. Both results were negative. I was wondering why isn't my period as heavy as normal. Even when I use the bathroom the blood doesn't come out. When i wipe myself after using the bathroom it is a very pale pinkISH RED on the napkin. The blood comes out sometimes. I use only 1-2 pads a day and normally i use about 4 or 5 around this time. Could I be pregnant even if the test results came out negative?
