I have been taking 2 progesterone tablets four times a day since I got my BFP. At 12 weeks I got to start weaning off them and have two days to go of only one tablet a day. I was definitely very bloated to begin with and really struggled with sleep at night, but I have also been having hcg injections so TBH don't know what is causing what. Since starting to wean off them I have had terrible headaches but I'm not sure if that's due to a change in the drug levels or just that its got hot here over the last few days.
