Hello. well i had my period on january 11th-16th then it came back on the 23rd but was much lighter (considering its usually pretty heavy) and it lasted 4 days i have a 24 day cycle so im a little late i took a pregnancy test on febuary 3rd it was negative it was a cvs brand. I have been getting headaches and cramps and back pain like my periods about to come on but it hasnt yet im very confused. Also about a week after i had the spotting i woke up one morning and a large amount of clear runny vaginal discharge came out of me. what could be the reason for this? am i pregnant?? also im 22
