What do I do?

Hello ladies! I’ve been talking to my doctor for the past few months about extremely long periods. They usually last up to a month. They give me the same runaround about how I have to take birth control if I want the long periods to end, and I really really don’t want to. Despite wanting to conceive, I’m on the verge of giving up. This has been my worst period thus far. They put me on metformin again, and I’ve been taking it for about 4 days again now. (I feel the sickness. Bleh.) Ive been bleeding for 2 months and within the last week, it’s gotten HEAVY. The clots are enough to fit in my palms, and when I go to take a shower, it’s running down my legs before I’ve gotten a chance to get in the shower at all. Just while I’m heating up the water. I feel faint all the time and ivealways had issues with my iron levels. Basically, I don’t think my baby dancing times line up at all, and I rarely ovulate, but do I see if this is a miscarriage? Is there a way to naturally stop the period on my own? I really don’t want to have to take birth control, but I’m not sure how much longer I can handle this. I just want a baby 💔
