Worried about spotting

Katie • 1st baby 👶🏼
I'm 7 weeks today! So I've been spotting on and off throughout the day for the last 4 days but this morning when I went to pee there was a lot more than there had been, it was more of a red colour than pink but no clots or heavy period like. 
I do have slight cramping but nothing to write home about and I have started to feel very sick this morning which is new as I've not really had any morning sickness yet! I'm still worried about the bleeding and I can't get in to see my doctor today so I might try and go the walk in centre just to get some reassurance that I'm not loosing this baby... I just don't feel right for the last few days I've felt there's something wrong and I just need to know!
