This isn’t the pregnancy I expected

Just a warning this is going to be kind of a long post but I need to get it all out. I’m currently 10 weeks and 3 days pregnant with our rainbow baby. My husband and I had two early miscarriages before this baby. We also have a 20 month old son who is our world. With my son I had severe preeclampsia and delivered at 34 weeks. I was hopeful that this would be a more normal pregnancy. But, I was so wrong. During my 8 week ultrasound they found a massive cyst on my left ovary at 16cm. I just went back to the doctor Monday for a follow up ultrasound and apt with my doctor. On Monday we found out the cyst has grown even larger and is now 20cm. My doctor has referred me to a GYN Oncologist because she said the cyst is huge and looks complicated, she also said there’s a small chance it could be a tumor since it’s grown so fast. She said she’s 95% sure everything will be okay with the baby and I’ll be able to carry and deliver the baby full term. But, since Monday my mind has been in circles. Hoping for the best but also thinking the worst. My appointment with the oncologist is Tuesday and I’m just praying for some good news finally. I’m terrified it might be ovarian cancer or something may happen to my precious baby. Regardless the oncologist is going to remove the cyst and it’ll be a major abdominal surgery, my doctor said it’ll probably be when I’m around 14 weeks, but I have to see what the oncologist says. Like I said, my mind is just in circles and I’m so worried. I want to enjoy this pregnancy and feel connected to this baby, but it’s been so hard with all this going on. I’m sorry for such a long post, I just needed to get it all out.
