I just had a baby 7 months ago and I leaking milk all over again am I pregnant

This questions can't be answered without asking if you breastfed your baby and for how long. If you have you may still be producing a certain amount of milk. Also, to answer if you are pregnant is a question of if you have missed periods, if you have had unprotected sex with your partner, etc.

If both of these questions are no and if you have concerns you should visit your Women's Health Care Nurse Practitioner or you can see your OB-GYN doctor and see if you can have a breast pap, yes, there is such a thing as a breast pap and it is simply done by placing a little bit of your breast discharge into a slide, spray it to fix the cells and send them for a lab. Evaluation, this will tell if the discharge is benign or if there is something to be concerned about. Also, the questions above in the first paragraph ought to be answered as a minimum to get an idea of your case. Good luck.
