Progesterone Suppositories - Do I?

[TTCROYGBIV]

I have been given progesterone suppositories for when I have a BFP. I’ve had a very questionable line on a FRER today at 7DPO.

However my last cycle my temps started dropping over 4 days from 10dpo, so I was worried about my progesterone dropping before implantation could fully take place.

I’m weighing up whether I should start taking the suppositories in the next day just in case? What are the cons?

Attached my FRER, last cycle chart and this cycle chart x

Anyone?

Why not? If you don’t get a BFP on the day your period is due, stop taking them. Your period may be delayed by a few days, that’s all. Plenty of women, including me, were advised to take them from CD 14. Good luck to you!

Could you ring your doctor? The progesterone can make you feel a little ropey and can delay your period, but so will pregnancy so if you think your test is positive it could be worth taking them for a couple of days?
I've only ever taken them for IVF so I'm not much help, but for IVF you take them from the day of embryo transfer (approx 5 dpo) until test date, and if you're not pregnant you just stop taking them, so I can't see that they would cause any harm if it's not a positive.
Hope someone more helpful comes along soon, and keeping my fingers crossed that this is your month!

Thank you ladies.

I might give them a go tomorrow and keep testing. If no BFP by 13dpo I’ll stop x
