On November 11 me and my boyfriend were grinding. He had no clothes on and I had a very thin pair of underwesr on the whole time. Before he came he lifted me up and moved me. He wiped the cum off of him and made sure to wipe his hands good. He made sure his hands were dry and after about 30 minutes or so he put his fingers in me. My period was not due until November 30. I started my period om November 28. I have had my period start early before but this time it is really light. I normally have a very heavy period. I took a pregnancy test last week it was negative. I took another pregnancy test on day 2 of my light period and its another negstive. Could i be pregnant or is my period just light due to me stressing out about this?
