My baby kitten..old enough to be a mom? PLZ HELP ME!

[Lgptv]

My baby kitten..Snapple...She is acting very weird... U see at night i lock her up with 2 other cats... 1 girl and 1 boy... The thing i am wondering is....she has been acting very weird lately...Fidgity, very emotional and affectionate, and not her spazzy crazy self...She has also been meowing very loudly. She will walk into a room far away form others and start meowing, as if she is trying to find someone or if she is in major pain. I dont know what to do...also Today she jumped onto my sofa and laid on a blanket then a while later got up and had peed... I dont know what to do....I also don't know...if she is old enough to have kittens...How do i tell if she's old enough and how old does a cat have to be to have kittens...I'm wondering if shes too young to have them but has them any way.. Please help me...

My only 2 thoughtful reasons for this weird behavior is..1 she's pregnant or 2 she has an infection... how do i tell????
Plz plz plz plz help me!

you sound like you want her to have kittens. Any female cat less than 2 years of age SHOULD NOT HAVE KITTENS.
If she's pregnant get her spayed and abort the litter. Get the others fixed too.
Chances are very good having a litter very young none of the kittens would survive and she's too young to be a good mom. You might find yourself having to feed newborn kittens every 2 hours.
Sounds like she might be in heat from your description.
Be a part of the solution, instead of part of the problem, and get her spayed.
