I am Trying to conceive and for the past week or so I have been having cramps off and on, mild lower back aches, a white creamy discharge, and today I have noticed a light brownish discharge. I am 13 DPO and AF is due in 1 or 2 days from now. HPT I took this morning was negative. Could this be implatation bleeding or is it just my AF playing tricks on me? I do not normally have these type of symptoms before my AF. Any info would be greatly appreciated. Thanks
