Low progesterone 7w

Sa

So I am 7w3d today, I started having some light pink spotting only when I wipe here and there at 5w4d so they had me come in at 6w6d for a ultrasound and baby was measuring 7w with a heart rate of 124 everything looked good. The spotting didn’t stop so I requested they check my progesterone levels which they did on Friday at 7weeks. Those results came back yesterday at 8.5 so definitely low. Already messaged my doctor so hoping to get supplements first thing Monday but just was curious if anyone has had a lower level this far along and things turned out okay? I feel like it’s reassuring that to this point baby is measuring good but so hard not to think the worst and spiral.
