Hopefully this wont be too long. If so, I apologize in advance

So back in July of last year, I started my period early, which has happened before so I did not think anything of it. But it did not stop after a week. After a few weeks of heavy bleeding, severe (almost crippling) back and abdominal pain, I went to see my GYN. He pretty much blew me off, didn't listen to much I said, and stuck me on birth control saying it would fix it. This continued on, every single day, up until the beginning of December. I had went to the gyn many times in between, kept blowing me off, said nothing was wrong at all, and then turned around and said they will just do a labroscopy (sp?). That seemed really off to me, so I switched doctors, and she upped my birth control and that had stopped.

So things went fine for a few months, then about a month ago, I got a UTI. Never had one before so I was not even sure what it was at first, but got that figured out, took antibiotics and it went away. And now I have gotten 2 more since then (so 3 in about 2 months total). I have an appt for the gyn for 2 weeks.

But today I noticed that my period came early again, but this time the blood is black. I am pretty worried at this point. Anyone had anything similar? Im starting to just think my body has gone haywire!
