Anyone taken progesterone suppositories?

I am 12dpo after 7.5mg of letrozole and feel like 💩.

BFN today, but have had terrible cramps and nipple soreness since 1dpo. Wondering who else has taken suppositories and if they made you feel awful too?? I’ll test again in two days and stop taking if BFN... just bummed out that it feels like all these pregnancy symptoms... ☹️
