I'm just curious and don't know if it's in my head or if I'm experiencing early pregnancy symptoms. I've still got 13 days until my period is due and I'm experiencing light sensations in my abdomen for the last few days. 3 days after my period I spotted light pink and then brown for 2 days..AlSo been sleeping more often than normal and having light headaches. could this mean I may potentially be pregnant or is it in my head? any suggestions??
