I need to know if anyone has found out they were pregnant after having similar symptoms. I had a weird period, spotting and then very light bleeding (very light pink in colour) last Tuesday night and then nothing and the same Wednesday night and then nothing. It was due last Thursday. Took a test Sunday morning, negative. Took another this morning, negative. I have been having cramping sensations at night when I lie on my side which go away when I sleep on my back. I had some stress a few months ago when I started my job but my period still came and I have been feeling more relaxed. We did have sex very close to when my fertile window was last month according to my period calendar. So I think I need to see a doctor to find out what's going on.
