Pregnant or not

Shaelee
Hello, I want to understand what other people did or went through. 
My last period began on March 18th. I am now two months late. I have taken three at home test that came back negative. My nipples have been sensitive, I feel sick here and there and have been really tired. 
I went to the gynocologist today and he did a urine test that came back negative. He came back in the room And immediately started talking about inducing my period and then starting me on a fertility drug. 
I have been trying to get pregnant for two years now and we did blood work a couple months ago and he said everything looked normal. And now he wants to put me on fertility meds. 
I feel really on edge about taking the pills because I don't know for sure if I not pregnant. He did a urine test which I know that not everyone shows positive when they are pregnant. I am confused as to why they wouldn't do a blood test. Why immediately induce my period?
Background, I am not always 100% on time with my period but I've never been this far off since before I was on the pill. I have been consistent since I started the pill 10 years ago. I stopped the pill almost two years ago or more because they were making me sick. 
Not sure what to do, I don't want to take the pill because what if I am pregnant?
