Spotting and cramping

I'm 6w and 6d today. Last night I noticed I had some slight light brown spotting that went away after a few wipes. Then when I was laying in bed I started getting cramps that felt like period cramps, the kind where you want to stay in bed with a heating pad on your stomach. I noticed they were mostly on the left side where my ovaries are. After googling and reading about ectopic pregnancies I became super nervous but I wasn't in THAT much pain so I went to sleep. When I woke up to pee this morning I happened to look in the toilet before I started peeing and saw more brown dripping from me, like when I first start my period. Two hours later and I'm still spotting (brown) but it's very minimal, like only when I wipe. I also still have cramping but it's not at bad as last night. Ive also noticed that I don't really have any symptoms of being pregnant like I did when I first found out I was preg at 5 weeks. I was really nauseous, tired, and my breasts were so full and sensitive. My breasts are still sensitive but not as much...that's really the only symptom I have now besides the spotting and cramping. I called my doctor and she said she would get the tests from the blood I left yesterday and call me back but that was a few hours ago. This is my first pregnancy and I'm really nervous. I'm trying not to think about it much but I can't help it. Has anyone else experienced this?
