Trying for baby #1

Stephanie • First born arrived 4-9-17. It's a girl💗Baby boy arrived 9-8-18💙
My husband and have been ttc since august with no luck. Joined glow community 2 months ago. I'm 9 dpo and having multiple symptoms of pregnancy. The only thing that would suggest I'm not preggers is my bbt's. My temp dropped on 7 dpo and has stayed down. Anyone got a bfp with low bbt?
