Heavy periods for more than an year.

I was not able to continue my pregnancy. I had a surgical abortion in 2018 and I was 7wks pregnant. I got my periods after the abortion and it lasts for few days. After the abortion, my periods are very heavy till now. Periods are very regular after the abortion. Before abortion, my periods are irregular and I miss few months. Now, it's very regular and it lasts for 4 to 5 days. The flow is very heavy for first 3 days. I sometimes see clots in the toilet during cycle day 1 and 2. The clots are not very big like lemon. Small ball size. I used to change pads every 5 hours from cd1 to cd3. This is the same every month after the abortion. Is this normal? What could be the problem? I didn't visit any gynecologist after that. So, I an just worried if this is any issues after abortion causing heavy flow periods with clots. Thank you.
