Bleeding at 7 weeks

I started spotting on Thursday afternoon. At first it was brown blood and very light and from everything I've read, it seemed like nothing to worry about. Yesterday it got a bit heavier and turned pink. I called my doctor's office and the RN told me to just wait it out and call back if it got heavier or didn't stop for 24 hours. So then this morning it was heavier (but still lighter than a light period day) and the blood was red and had some clots. I called again and spoke to the OBGYN on call and he told me if I wasn't bleeding enough to fill a pad every hour or wasn't having cramps there was no reason to come in. So I guess I'm just wondering if anyone has experienced anything similar? If so, did you have a healthy pregnancy/baby?
