Weird this time

I came on my cycle 3/24 in time but I had 2 1/2 days of medium bleeding then light then last day (3/29) spotting. Well next day all the way up to exactly a week afterwards, I spotted and bled very lightly. Id only see light flow while havin something tight around my stomach, after sex or after masterbation (tmi sorry)... Been very tired for 3 weeks, frequent urination and queasiness. Now 2 days later lots of creamy wet discharge. Anybody ever experienced this?????
