Suggest Remedy For Periods Problems

I am 25 years old, I had my daughter August 2nd of this year (2011), my period has been really strange lately. At first after my daughter I was having large clots but I went to my doctor and he said I was fine. I still have sex with my husband regularly (aside from during periods, we don't then.) My period is really watery and it's like looking at real blood really, like if I cut myself which I'm clumsy; it looks almost like that. And there is no smell at all. This was after my period, I noticed it slowed down then it just started back up again. Keeping in mind, my daughter was born 3 months ago. I have also been feeling dizzy and a bit ill with a bit of a temperature. The hospital is really far and I don't drive so I'm kind of screwed here, I also work from 830am-5pm every day (aside from weekends) so it's really hard to get myself down to a doctor. I'm kind of worried and unsure what to do. After me and my husband had sex I started bleeding again. Is this normal or is this something that really needs to be checked out as soon as possible?
