Sex after baby

It's been 3 1/2 months since I had my daughter via c-section. I'm on Prozac for post partum depression. I have the implant. I haven't been in the mood at all for sex with my husband. Not sure if it's my hormones, the Prozac, or just my brain having a hard time differentiating between being a mom and being sexual. I don't have any problem with giving oral sex or hand jobs, but I don't really want to be touched except to snuggle. Any advice?
