Spotting... Again... 5 weeks...

A few days after I got my positive I started having very light pink spotting that lasted about 2 days and that was a week and a half ago. Still been having all the preggo symptoms but last night I had a little bit of pink when I wiped it stopped and it's back again tonight, just a little bit not alot, no heavy cramping just mild that comes and goes throughout the day. Anyone have this and be ok? This is baby #3 and I never had spotting with my others.
