My periods started going wonky at about 38 years old. I started getting really heavy periods that would last much longer than usual. And I'd go longer between them for a few cycles then it seemed like I'd only go a few weeks before getting my period. That has been going on for 5 years now and for the last year I've been having more clots.
My doctor decided 3 years ago to do an ultrasound of my uterus to check the cause of the heavy bleeding. She said it was possible I was forming fibroids. She really doubted that I was starting menopause or even perimenopause. The ultrasound came back clear. They recommended birth control for the bleeding and to make my periods more regular. But since I wanted more options (I really wanted to save birth control as a last option for various reasons) my doctor told me to take 600mg of Advil every 6 hours for a few days before my period and during my period. That really did help for the last 3 years with the amount of bleeding (which was making me anemic). But lately I've noticed my hormones are all over the place and I'm getting terrible cramping with my period. It's so bad that taking Advil doesn't make any difference. I've started taking progesterone birthcontrol to help regulate the hormones. It shouldn't have any impact on the timing of my wonky periods but it should keep the lining of my uterus thinner and help with the blood loss. The next step after this would be to consider an iud or ablation.
I guess my point is that based on my experience, it is very possible you are starting perimenopause. My doctor thought I was too young but now I am sure that is what I was beginning to go through 5 years ago. Or your irregular periods are a result of your stopping birth control and it will take some time for them to even out. Or maybe you have something else like fibroids or endometriosis that are causing the bleeding and clotting. i think I'd ask the doctor about those possibilities.
