Progesterone Cream and BFP

Nicola • I`m a 32 year old teacher from the UK. Had my rainbow baby in September 2017 after miscarrying twice. Had a chemical pregnancy in January and now TTC #2
I had my BFP yesterday and this cycle I've been using progesterone cream as I have a short leutal phase and miscarried in March. I've read that I need to keep using it til 20 weeks. Anyone used it?
