Spotting

Hi everyone just a query for anyone that can help answer it, basically I am 5 weeks and 6 days pregnant today and on Friday and Saturday I noticed light brown spotting on my underwear. I had no pain during the time so didn't even realise it was there. There wasn't a lot maybe 2-5 small drops in total over the two days. Sunday I had nothing and then again Monday one spot on my underwear again light brown in colour and clear water like discharge. I went to the walk in centre on Friday to just clear any doubts, but that didn't help much at all. I called the Early Pregnancy Unit as the doctor said try and get a scan but the want a doctors referral, my doctor as no appointments until after the new year now. So I am confused on what I should do? I have read countless posts on its normal and as long as it's not red and painful it's okay but just wanted someone to say it to me 🙄. Any ideas what's happening?
