should I pregnancy test?

Angela
I had an ectopic back in december. I had a period (what I think was a period) on feb 7. That was the first period since my ectopic and only lasted 3.5-4 days. No clots and hardly anything-no cramps. I've recently been using the CVS OPKs and all have come back positive the last 4 days. Should I pregnancy test? Or to soon? 
Comments greatly appreciated!
Thanks loves
