if you can get all people together to do it at one time it would be cheaper than going in 3 separate times. Canadian Biologics does DNA testing at least they use to.

Figure out your ovulation and go from there. Semen can only live in you for 7 days so if you figure out your ovulation then use that week as the time reference

The way i found out that i wasn't the father was i used an at home test. Its the cheapest and fastest way and was only $100.00. After i got that result back saying i wasnt the father i went to licenced clinic and paid $500 to verify the initial results. Way more expensive but its court approved and verifes my initial findings. Its something you can consider.  
 
Thank you for going the route of getting the test done instead of lying for 4 years and making the wrong man have to oay support.  
 
If you want info in the first clinic i used, pm me. The second one (more expensive vut licenced) was rejuvenate spa in victoria. The owner is an amazing and professional woman nammed Tannis. Shes so helpful it was good to have the support

To the previous, but no longer posted comments, that assumed I was the one who had 3 relationships with 3 different men, no where in my comment did I say that. Truth be known I am the child with 3 possible dads. My relatives practically raised me and my mom has passed on. I am just starting to wonder. Thanks for all the other comments.

I hope you soon find the answer you are looking for and I think it was wonderful for you to reach out for help in this matter. Please do not let negativity prevent you from turning to others for help.

So eye color and blood types can be used to rule some people out for sure depending.  
 
If it works then you cold just do a test on the likely guy.  
 
blue eyed people have blue eyed kids.  
Two people with O blood have a kids with O blood.  
But 2 brown eyed people could still have a blue eyed kid  
Were you RH- ... if baby was RH- too the dad had to be also.  
 
You should be able to google some of those.

From what I can tell, cheaper options have a lesser degree of certainty. That is why the courts generally require the costlier more time consuming options.  
 
If you are comfortable with having a pretty good idea, the cheaper options may suffice. If you feel you need to know beyond a shadow of a doubt or if this may involve legal action at a later date, I would spring for the more expensive options.  
 
Either way, best of luck to you.
