Hey y'all I'm 15dpo today😁 at CD 31 period was due yesterday😋 and online websites says for me to test today🤗 but fertility friend says if I don't get a period by 16-18dpo then I could most likely be pregnant.😄 Since taking the progesterone shots I've never been late I've always had the 13day luteal phase which means that by 13-14dpo I'm getting my period😏 but here I am 2 days past 13dpo and no period🤔 other patterns suggest that usually 7-9 days after my last progesterone shot I usually get my period 😥so today is day 7 so we shall see day 9 would be Friday.😓
