You may be becoming anemic because of the blood loss which happens to people with severe fibroids, endometriosis, or unfortunate situations like this - that would explain the extreme tiredness and lightheadedness. Although it is a serious issue, my doctor has treated it in me with iron supplements because it's been a slight and temporary case.

I have had the long-term bleeding happen because I didn't take my pills on schedule and I have also gone 2.5 months without a period because I stopped a pack midway through as well. My doctor explained that I had more or less confused my body by starting a cyclical hormone and not finishing it and that since it was a rare occurrence in me rather than a constant happening, it wasn't particularly dangerous beyond the slight anemia.

What I do find odd is that your doctor wouldn't see you because you were bleeding? I've had several exams in-office for both incessant bleeding and to even ultrasounds to peek at a swelling ovarian cyst while bleeding and from what I could tell, it was near routine for the doctors and nurses. An annual exam and pap smear shouldn't be done under these conditions, but they can certainly still examine you when there's a problem.

When I had stopped bleeding, my doctor prescribed a drug to cause my period to start but he told me to give my body one more week to start on its own before starting them and thankfully it did start before that. When I couldn't stop bleeding, he left it untreated but continually tested my blood to be sure my iron levels were high enough, and examined me just to make sure nothing else was going on. It did, unfortunately, take about 3 weeks to stop.

I'm not a medical professional, this is all simply based on personal experience. If I were in your shoes, I would find a new doctor, and once this issue is resolved, would bring up the fact that your cycle has changed since childbirth...they may be able to prescribe a different birth control pill that will be more effective in regulating you, but without side effects.

Good luck!
