Okay so my last two periods were odd... they were late, lighter, and shorter than normal. Plus I didn't have any clots. Here lately I've been way more exhausted then normal, eat more than normal, and have crazy headaches, every now and then I have back pain. Also I've been wanting pickles. I also seem to smell things someone else doesnt. A few days ago I took two blue dye test and thought I saw a line but you could really only see it in person and it was so faint I just thought it was an indent or evap line. My question is could I still possibly be pregnant even if I had my period or is it all in my head?
