Due on today. 12 DPO of 24 day cycle. BD'd every fertile day. Had brown sludgy spotting since yesterday, no need for a tampon. Now pinky watery stuff. Am usually very heavy. Cervix so soft I cannot even feel it! Boobs normally painful in run up to AF but only started hurting yesterday. Tested today - 2 x bfns :( any advice gratefully recieved. Am at my wits end.
