is it worth it?

Hello ladies, I'm 26 with PCOS I'm on metformin and I just finished my letrozole 2.5 mg and my progesterone this is my first month taking letrozole and I finally had a great period after not having one for 10 months! Here's the question my husband is getting his sperm tested on the 14 th of this month right when glow says it's my highest day for ovulation. I would like to buy the clear blue digital monitor to see when I'm actually ovulating but my husband says don't get it until his test results get back because he might have a problem....should I buy it? 
Side note: we have been married for 7 years and long distance on and off due to our marriage visa for him to come live here. We have been TTC for a year and a half now because his visa was finally approved but I've had baby fever since the day we got married
