I wish hope this is worth waiting for is worth

I am so disappointed with the company that I applied to. They offered me a job that I really wanted. I am so excited because my recruiter told me that I will be starting April 13th, but when she called again last April 7th, she said that they already received my medical ( what do you want to say here? Your "physical") and it was ok. The only thing she needs to do is to finish my background check. They call all of my previoius employers before, she needs to know the number of my employers that I've left had for a the past year.After that, she never called me again. I don't know if I failed the background check, and now I don't think know If I need to apply and look for another job again, or I'll just wait for their them to call or message me. I want that job and I don't want to apply for another one then when I have already applied to another job they that will call me, that this always happen to me.
