:o I have 2 boys and I really want to have a baby girl but I am still breastfeeding my 4 month old and my period has not restarted. How else can I tell that I am ovulating so that I can have my baby girl??

Firstly You can't decide weather your having a boy or a girl remember it's the mans sperm that decides the sex of the baby.
Do you not think you should let your body recover from the birth of your son before you try for another it doesn't do you any good. Your body will return to its cycle when its good and ready.
Although saying all this my girlfriend just had her fourth child and that's 4 months old and she just descovered she is pregnant with the 5th good luck I say I can think of better things to be putting my body through that close together.

I would try having sex before you ovulate and not at all after... I didn't try this and now I wish I had... I am still hoping that I'm having a girl but I am expecting a boy

If you really want a girl try the SHETTLES method, I've been looking in to it because I'm trying 4 baby no.2.I have a 3 1/2 yr old boy and would really like a girl to complete the picture. Go to Pregnancy Tests and Ovulation Test Kits from BabyHopes.com. Good luck:) :)
