First period after baby really heavy?

I finally got my period after having my baby almost three months ago...But the thing is, it's soo freaking heavy it's ridiculous and starting to creep me out. The first day I got it it was normal, but that night around eight o' clock I started leaking through a regular sized tampon. I thought I might have just left it in there too long but it wasn't the case, it was only in there for about two hours I believe. So having just moved I couldn't find my pads and my clean underwear so I just made due with the tampon. And I woke up after going to bed around nine o' clock around four and my pants were soaked and the tampon was completely filled. It was so gross. So I had to wait until the pharmacy opened at eleven in order to get some super sized tampons so just made due with my regular. After waking up at four o' clock I was changing my regular sized tampon every hour!! I was still soaking through when I'd change it within the hour. So I got some super sized tampons and worked (unfortunately that sucked) and then three hours after putting the super sized one in I was leaking through! I called and spoke to an OB nurse at the hospital I delivered at and she said ti was possible that it was so heavy because I hadn't had my period in almost a year, or that if there was any clotting that it might be left over placenta. I haven't seen any clotting and she said if it didn't stop then I should probably go in and if it was happening to her she'd come in to the hospital. After I spoke with her, I changed my second super tampon just short of 3 hours later and I was soaking through, not heavily like before but just starting too. There was some in my pad. So I decided to wait it out thinking that maybe it was going to stop. I changed it again at about nine thirty last night and took a shower trying to not panic. (The sight of all the blood was grossing me out super bad). Then, I didn't leak through much during my six hours of sleep, then had to work. Got off work at six thirty am then went home and took a nap. I changed my super tampon six hours later and was majorly leaked through. My pad looked like my normal period if I wore a pad.

I know this is probably stupid and I shouldn't be freaking out but my periods are never this heavy! I mean, they've been heavy before but they stop after a few hours and a regular tampon always did it for me, never a super. I've also talked to my mom about it and her periods are always like this she says but with a super plus tampon and it leaks through every hour. She has gone to the doctor for it and is on birth control and nothing really seems to help, and she says after having a baby things can change and go screwy with your body. I don't feel lightheaded or sick or anything. Just grossed out and kinda freaked because of all the blood I'm losing. I don't have bad cramps or anything, which is kinda odd but super nice. I mean, they're there sometimes but not bad.

Would you go to the doctor? Was this normal for you after the birth of your child? I just don't want to be stupid and go to the doctor for something that isn't a big deal...

Please don't be rude. You know what it's like to be on your period, all emotional and touchy and everything...
