Progesterone was 15

Is that low for 4 - 5 weeks? My doctor said it was the lower range of normal and she’d like to see it higher but I’m so early I figured it was fine. So she gave me progesterone capsules to start which I did but idk if this is normal or not.

My hcg was 353 last Tuesday and 1029 on Thursday, and she did not test again. But I feel like I’ve stopped having nausea and tender breasts so I’m kinda worried

Any reassurance? <3
