So excited and nervous

I just found out I’m pregnant. We have a six month old miracle baby and three older kids (all girls). Since it was so hard to conceive our sweet Shiloh I just didn’t think we’d ever get pregnant again. But here we are I’m so happy but scared to be happy if that even makes sense. My husband is also thrilled but we know at my age and with my medical history there’s a 50/50 chance that we will actually have a baby. I’m just praying this sweet baby sticks. I would love to have someone for Shiloh to grow up with especially since her sisters are so much older than her. I’m not telling family or friends till we pass three months so I’m so grateful I can post here and share my happy/nervousness.
