I think my pregnancy amplified my melanoma. My melanoma on my back grew significantly during my pregnancy (at the time I just thought that's what moles did during pregnancy) and I was diagnosed 3a, 2 months post partum. I am four months out from that, and as of now I do not want to risk another pregnancy. With yours being stage 1, you are likely cured, so like the others I would go with your gut on it.
