Anemic problem!!!!

I've had been anemic for couple years now and I've experienced really heavy bleeding that lasts months!!! It's gotten to the point where I have to wear the full on diaper type pads for security & protection!!! I feel so hopeless & my doc had told me last year that it's going to be very hard TTC!!! That hasn't stopped me from believing because I know it's all in God's timing. I've been TTC with my husband for 6 years now!! Has anyone experienced this and still got prego????? Advice please!!!!!
