sheila I think if someone has been regularly taking progesterone every month and has found it out of sync with their bleeding every time, then there's no harm in trying to get it to sync with their own body - they are getting enough, overall.
But if someone hasn't taken any progesterone for 3 entire months, the bleeding isn't anything to do with a period, especially if it is happening 2 weeks after the last bleed (a 'period' is what happens after successful ovulation, it doesn't just mean 'a bleed' and you won't have ovulated if you are bleeding 2 weeks later...). Instead the bleeding is because their lining has built up too much - which is the risk factor for endometrial/uterine cancer and is what progesterone prevents.
Progesterone thins the lining of the uterus, that is its function. Since there is now considerable build up, it's imperative that enough progesterone is taken to get rid of that extra build up and help the body to shed it - or it is a risk for uterine cancer. Taking progesterone for a few days and stopping again because you start to bleed, is not going to work - you need to keep taking it, so it can thin that lining.
But it is also a bit scandalous that someone has been in the position for this to happen and is unable to access medical help to get advice or more progesterone....
By the way, KaraShannon, if norethisterone works for you, the BMS have some info at the bottom of this pdf about using it for the progesterone:
https://thebms.org.uk/wp-content/uploads/2021/10/14-BMS-TfC-Progestogens-and-endometrial-protection-01H.pdf "Norethisterone
5 mg for 12 days a month (cyclical) [given that no smaller (1-2 mg) dose stand-alone norethisterone preparations are available in the UK]
0.5-1 mg a day (continuous combined)
– Off license use of norethisterone in progestogen only contraceptive pills (e.g. Noriday 3 x tablets of 350
micrograms a day, will provide 1.05 mg of norethisterone) may be considered as an equivalent alternative."
Which means that officially you can use the Noriday POP x3 tablets daily (which is norethisterone) if you are really stuck, but you need to speak to a GP ASAP to get onto a progesterone.....
