Is it possible to get my implants removed while I am pregnant (4 weeks)?

hello, i just found out i am 4 weeks pregnant. I have 500 cc saline implant in front of the muscle for 11 years now. I am 37 years old and i would like to get them removed . is this a possibility? i have 2 older children from before my implants and my breasts got so big and so painful it was very hard to deal with so i cant even imagine 9 months pregnant WITH 500 cc's. Thanks for your time :)
