Has anyone felt this way?

I’m going to (hopefully) be real careful with the way I word this because I don’t want to seem like I’m ungrateful .. truly, I feel so incredibly blessed .. but this is my situation I’m in currently. & the only reason I’m posting is because I’m wondering if anyone has felt like this before .. I just want to know that I’m not alone.

My husband and I recently found out that we are expecting our third baby! We had been trying for our third for nearly three years. Over those years, I’ve experienced heartache after heartache each month when seeing all of those negative tests, and watching everyone around me get pregnant, felt like a slap in the face although I was actually so happy for them. I just wanted that to be me so badly. Anyway, I found out three days ago that I am pregnant. My initial reaction was pure excitement and shock, and so was my husbands. But I felt like my feelings quickly changed to mostly fear and worry. Don’t get me wrong, the excitement is still there but I didn’t expect to feel scared, nervous of the unknown .. for example like: will the baby be healthy, will I make it to full term, will our kids adjust to the baby well (they’ll be 6 & 8 once baby comes) and the list goes on.. but those are my biggest worries that I have. I know I should be bringing this up to my doctor and I will but for now, I just wanted to post and see if any other mommas weren’t exactly on cloud 9 after finding out that they are pregnant? I truly believe I’ll get there.. I just think my hormones are all over the place which is resulting me to feel this way. I really hope this doesn’t seem like such a negative post, that is really not my intention at all. 😊
