Help spotting at 6weeks

Natasha

I'm 6weeks pregnant and I had implantation bleed at 4weeks,had a little spotting again at 5 weeks, and I had spotting again on Saturday and a little bit today, I can't have a early scan as it's not classed as priority atm... Anyone else experience this and all was okay, iv had 3 chemicals so far this year and a mmc back in 2016
