Last month I was 16 days late with brown spotting on the fifth day, which has never happened to me before. On day 16, I started bleeding lighter than normal. I didn t pass any clots or tissue like normal, and I only had mild cramps versus my normal cramps. I ve had a lot of other symptoms like my nipples tingling. Now I keep felling flutters in my lower abdomen. My question is, could I be pregnant.
