Is this the start of a miscarriage?

Kate 🤰

I’m currently 6 weeks 5 days and woke up this morning to a dull ache in my lower stomach and this when I go to the toilet and wipe. I have put a pad on but I don’t seem to be bleeding into it? It’s a Sunday and I rang out of hours GP who said to go to my nearest EPU but they only open Monday-Friday? I’ll wait until tomorrow but do you think this is the start of a loss?
