I think im 4 days late

Cycles were as followed

8/1-8/4

8/24-8/28

Bd on the 1st spotted a little which was on and off till the 4th.

On the 6th i woke up and went pee and wiped blood so i put a tampon in. About 2 hours later i checked for the flow and it wasnt heavy enough for a tampon. And the spotting got lighter until it stopped early morning on the 10th. I got a blood test done on the 15th for pregnancy (came back negative) and my next period was supposed to start on 17th and i havent had anything but creamy white discharge.
