HCG Levels rising slowly

Taylor • 25. Wife. Mommy to my little mermaid (5-30-18) 🧜🏻‍♀️. Step-Mom and Fur Mom.

Anyone else have a similar experience and it turned out okay? Here are my levels:

Thursday at 4:30 pm: 202

Sat at 8 am: 259

Monday at 12 pm: 432

Wednesday at 12 pm: 497

The only time over 48 hours was the sat-mon. Do I just need more time? The most recent one was only a 15% increase and I'm really worried. My mid-wife is very slow to respond. Thanks!
