I just saw you posted below about having been on E2 and P4 support through 20 weeks.
I too am PG with Dr. Check and he has me on P4 still. I just turned 20 weeks this past Thursday. He wants me on it until 36 weeks because every time they take me off the P4 my level drops to low 20s. I'll be speaking with him tonight but I'm curious to know what led to you finally being weaned off at 20 weeks.
Thanks for any info.
