Hi Slouise and LM.I may be in the same situation as both of you...I am new to this site as we have just started our TTC #1 journey. I am 36 and was on Cerazette for approx. 7 years. My last pill was on October 17th 2019 and I had my first bleed 27 days after that with a positive ovulation on CD13. I was feeling very pleased with myself! I have had 2 periods since then, the fisr was 25 days with ovulation on CD21 and the second period was 27 days with ovulation maybe CD23 (I didn't really track/detect ovulation in December). We had decided to TTC from January 2020 so I haven't been too worried up until now. I thought that because Cerazette is a progesterone-only pill that it might take my body a while to start producing progesterone on its own again hence my short luteal phase. I started taking 100mg of Vitamin B6 this month and also plan to incresse my Vitamin C intake as I have read that both, especially Vitamin C can help with luteal phase/progesterone. I would love to know if any other ladies have experienced a very short luteal phase after stopping Cerazette or another POP and, most importantly if it increased within a few months of stopping BC? Baby dust to all.
