Should I test?

Okay my periods are never regular but they sort of regulated at the beginning of the year. So when I got some positive ovulation we went for it. Well I posted my list view of my recent cycles. I haven't had a period since March 27th and I tested on May 6th when I went to the hospital for extreme nausea for a week. It was negative and the doc said my Gerd caused the nausea but it still come and go. So I spotted on the 2nd, 3rd and 4th of June and now it's gone. The spotting only showed when I wiped. What should I do ladies?
