I had my son 10 weeks ago and stopped bleeding after 4. At our 8 week checkup my doctor put me on yaz-flex. The day of our app I started bleeding very light so I took the pill. Have been taking it for 14 days now and for the last week the bleeding has got heavier and heavier. I didn't get a Pap smear done due to bleeding. Is this normal or could it be from the birth. Please help
