Idk if anyone can help please read

Hi. I’m not sure if anybody can help but advice or opinions are really what I need. I was on the patch birth control for only a month in January and I didn’t like it so I stopped. My period came normally like it would that month and the next and then out of no where I started bleeding for 2 months straight from mid February- end of March. I did go to the obgyn for this and they kinda pushed it off like it was the birth control and only did an ultrasound and said everything looks great. I have history of uterine cancers in my family & I demanded and wanted more tests but they said no. I went to the ER and waited for 4 hours in pain and still didn’t get seen so I left. I went to urgent care they couldn’t do nothing. I’m literally in so much pain it’s affecting my daily life. I have a baby and I need to get up and take care of him. This month of April I never got my period besides blood clotting and it’s literally like black. I have the WORST sharp stabbing pains down in the pelvic area and when I press on it it hurts. I’m so frustrated to this point and I know nobody can give me medical advice BUT if someone had ANYTHING similar and can maybe give some ideas or opinons it would be really nice. I plan on going back to my doctor and demanding more tests tomorrow also. I just really needed to vent also because I am just so annoyed.
