My period was suppose to come the 4th. It didnt. Well last night around 11 I woke up.and felt like I started my period, just the feeling, well a couple times before that it was just cm. So instead of having to get up and walk all the way to the bathroom I stuck my finger down there and there was blood so I put a pad on and went back to bed. Well this morning I have used the restroom twice and there's no blood on the pad, in the toilet, or when wiped. Could it have been implantation? I know on the 14th and 15th I had ewcm. Just no period so far this month.
