Pink spotting at 5wks 4days

Hi ladies, I'm having a bit of a flap.. So I'm 35 with 3 children with my ex husband. I remarried 6 years ago this and We found out last week we were pregnant again after 10 miscarriages over the course of the last 4 year. Last night before bed I noticed a bit of very light pink tinged staining on the toilet roll after wiping (it's a terrible habit of looking after I wipe but after what we've been through I can't help it) I wore a sanitary pad to bed last night and there was nothing on it when I used the bathroom this morning but there was light pink "spotting" again when I wiped. I'd usually call EPAU but I'm self isolating until Saturday as my husband and daughter are both covid positive so I'm honestly not sure what to do or shall I just do nothing? I'm booked for an early scan on Tuesday morning due to being do high risk. Thanks in advance. Kim
