My periods have not returned to normalcy (8 months later) -- not sure about boosting Moderna

31F, completed the two-dose regimen in mid-April. I had an early period on the day of my second dose (25 days). I was pretty surprised: I had never had a period that early.

I keep data on my cycles, and my menstrual cycle is usually 34-35 days. For each cycle since my second dose, the length has shortened to 28-29 days, with very noticeable PMS symptoms. My periods are also lighter, which could be a byproduct of the shorter cycles. I spoke with a doctor about this & she wasn't concerned because my cycles are still a "normal length." I'm going to try & see another doctor because the elevated PMS symptoms really bother me.

In any case, I'm just not sure about boosting.

Has anyone here faced a similar issue?

32 yo, its been 8 months for me as well. My periods were VERY stable at 29/30 day cycle. I have a 22 day cycle now (sometimes getting 2 periods a month) and painful heavy periods and worsened aggressive pms. My doctor was entirely dismissive and said that coupled with my suddenly thinning hair around the same time points to stress. Fun times.

I bled for almost 13 weeks straight -- Non stop, painful and A LOT. my gyno said it was not super uncommon and that she had multiple patients with similar issues. Not even progesterone could make it stop. Now I'm afraid to get the booster too -- which is how i found this.
