4 Miscarriages. 5th Pregnancy now on Progesterone

Hey ladies. I'm new to this. I was wondering if I should even download this app and acknowledge I'm pregnant after so much heart ache previously. This time I'm taking progesterone but my anxieties are through the roof after having a scan on Saturday. I was showing 4-5 weeks so obviously nothing could be seen. My HCG was tested and it's being retested tomorrow so I will know by tomorrow if my levels are increasing. Just wondered if any of you had success after previous losses with progesterone? Thank you xx 💖
