Okay so I really need help, I'm 28 and pregnant now..

Today's date is 27/02/2013 , so here's the story I didn't know when my last period was so we couldn't tell my due date for certain:( but they say its around 26 may 2013 of this year.on July 13th I had unprotected sex with my ex boyfriend? But if it was his baby I'm sure I'd be due around April the 5th am I correct? So it can't be his baby right? Then a couple of weeks later I had sex with my boyfriend at the time and this continued we would have sex a lot for months so I had no period etc before September then on the 3rd September 2012 I had sex with my ex boyfriend again but if it can't be his baby right because I had no period weeks before sleeping with him? So this would mean my baby's dad is the person I explained as my 'current boyfriend' am I correct?! Please don't tell me to get a dna test etc their must be some way someone can help me work this out!! Please help its really stressful

There is no way to know without a shadow of a doubt who the father is. You will have to have a paternity test done once the baby is born to determine who fathered your baby.

I have to be honest here... I read your question a few times and it is incredibly confusing. The lack of punctuation makes it tough to tell what is what. Then we have trouble with who is who and when you did what with who.

So as far as I'm reading it, it's impossible to tell who is the father... maybe if you make the question more clear it will be easier but I really doubt it and at that point, you really have no choice but to have a DNA test to be positive.

Once I know my due date for certain could I then check when the baby was conceived?? I had my period after having sex with my ex on July 13th but then when I slept with current boyfriend had no period after that then slept with someone on the 3rd September but I was already getting morning sickness and had no period before this so this would mean my baby's dad was my current boyfriend according to an online doctor?

If I'm due may 27th when was my baby conceived

Probably around August or September.

I'm sorry, but you will need a DNA test to determine paternity. It is impossible to know exactly the moment, or day, of conception.
