Has anyone else beed for 7 months straight ?

Im worried I can't have any more kids after the birth of my son I bleed heavy for 7 months straight I've been to many doctors and none of them could give me a straight answer as to why im bleeding like this for the most part they said my hormones are way off but now that my son is 2 years old we want to try for another one iys been 5 months and were still not pregnant yes were tracking my ovulation but im concerned I can't have kids do to the bleeding I endured has anyone else had this happen to them and was still able to conceive?
