Very scared please help

I am 35 always has normal on time periods. This time period started out on time normal. I noticed it was heavier than usual sometime just clots when i went to the bathroom. Then when it was supposed to be over it was still bleeding very light blood for two more days. I thought it stopped but today when i wiped light blood. For twelve days now. The scariest is that for over a week ive had pain like i have been holding in urine lower back pain into sides and front and very gassy and today bloated. I am not able to afford to see a dr and my anxiety is making me worry i have ovarian cancer. Please help could this be something not as bad or am i gonna die

anybody i really want know if anyone has had this prob and it wasnt bad
