I do understand that you would like to have another baby. The calls of motherhood can be very strong.

However, I don't think that doing so behind your partner's back would be a good idea. It can and will cause havoc on your relationship, especially if he knows you have that implant and then you turn up pregnant. He's going to feel mighty betrayed. You don't want to raise kiddos when your relationship is shaky.

Have you discussed this with your partner?

Also spacing babies out a bit more is healthier for your poor body! Pregnancy is rough on the body. Let it heal up and get stronger again. =)
