Spotting from the start :(

Jade
Hi ladies, 
I've been spotting on and off now since I found I was pregnant (now 7 weeks). I've read so much stuff online but so much of it is conflicting. I've noticed that lately during the working week the spotting 'flares up' and over the weekend when I rest it subsides... Any advice? 
I do have a long journey in to work(2.5 hours each way) but when I get there it is only an office job). 
Finally have a doc app tomorrow so I am hoping I get some reassurance then too...do you think this is something you can be singed off for if it is proven to be affecting mine and my little blueberry' health?
