i am 21 years old, my boyfriend and i have been trying for a baby for 6 months, my period last month was different that usual, usually it is red and heavy and lasts 5 days but last month it was dark and not heavy...this month i am due my period yesterday but it hasnt come, ionstead today and yesterday i have had cramps (like period) but instead of period blood ive had a clear gooey discharge, what is this? i think its too early to take pregnancy test, is there a chance i could be pregnant? is this a sign?
