Hi, we are currently pregnant after our 3rd fresh round of IVF - I'm just 5w2days. I'm totally terrified of miscarriage having finally got this far, and don't know if I should contact my clinic or not. Reason I'm wondering is that despite no real bleeding (had a spot of blood on progesterone applicator the other day, but nothing else) and only mild cramping, I have been taking my BBT every morning as usual (I have an ava bracelet that does it for you, so it's v easy) and I have noticed a scary downward trend for the last 4 days... 
Has anyone tracked their BBT and had this and things be ok? I need some hope... see chart attached. Thanks x
