Hello, I am at 5 weeks too. I have been spotting since 2 weeks ago when I found out my pregnancy, from brown spotting it changes to red. Went A&E two days back for this, they did a scan but baby was too small to see, but was given duphaston for a month. Two days already I am still spotting , waiting patiently to see a gynae next wed :( I was spotting on and off my previous pregnancy but not as bad this time. I have a 2yo baby boy.
But if is bright red I suggest you can head down to any gynae clinic to get a scan and blood test. Sometimes it can be more serious like ectopic
