First rainbow baby … maybe..

I had a miscarriage of my first pregnancy at 7 weeks in February and just found out I’m 5 weeks pregnant … I just had the lightest amount of spotting and I already lost hope that I’ll be able to carry for two more weeks let alone 9 months . It might not be a miscarriage this time but I have no confidence that it isn’t.

Should I be concerned of the one time spotting ?
