should I??

I was diagnosed with PCOS about 6 months ago but I've always had irregular periods. I have a 9 year old and was on birth control when I conceived with her. antibiotics did the trick! My husband and I have been trying and I had a cycle last month. I did NOT have one this month. I have heartburn like crazy and just feel like ick! my hormones are all over the place and I have acne which is completely out of the norm. He says to take a test but I don't want to waste a test knowing it's most likely negative because of the PCOS. Should I take it anyway?
