21 Weeks and Beyond Terrified!

I went to the doctor today for my monthly check up and told them about my recent nausea and vomiting symptom. I let them know some days it's bad and others its fine. I told them how I was fine in the first trimester and the vomiting developed once I hit my second. I was asked if I'm having headaches, I said yes in the morning. They took my blood pressure 2x, and it was high (Normally its normal). The doctor gave me a medical container to urinate in for 24hrs to check for protein in my urine and come back on Friday to check my BP/Blood. She said she wants to make sure it's not preeclampsia. Now I'm petrified. I'm trying to keep it together in front of my husband, as he is clueless to what preeclampsia is. I'm only 21 weeks, what happens if I have it this early on???

I'm scared my baby won't make it to full term 😪
