Heavy period tips?

Hi everyone, ever since I've had my daughter and my periods regulated about a year ago my period has been very heavy the first two days. But it's not a constant flow -TMI WARNING- it just splurges out for a minute at random times and stops and does it again multiple times throughout the day. So I inevitably leak unless I run to the bathroom fast enough to catch it before it leaks so usually I just confine myself inside the house until the two days are up. I'm afraid to go out and leak. I only use pads because I find tampons uncomfortable to use, hurt, and they just make me nevous. So does anyone have any tips and does this happen to anyone else?
