Follow up on Ectopic Scare!

So I made a post freaking out about what the doctors told me at the ER during my visit. At that time I was, by this app, 4 Weeks +3. They did a transvaginal scan and saw nothing in my utuerus but something on my ovary. They deemed that baby or a cyst... But freaked me out saying I may lose my child. My HCG then was 600, and they wanted me to be seen by the OB today (Tuesday) instead of waiting until Thursday. I'm doing a quantitative HCG test today to see if my levels have increased! I've been talking to my little peanut, making sure he/she knows that mommy and daddy loves them and hope everything's okay. Pray for me! I'm starting to feel anxious all over again.
