I check temperature myself also think that I have 高溫期短 problem(10 days m come).
After checking hormones, I have high prolactin level, it also affect the 黃體期 and 遲排卵. And now I have to take pills (Bromocriptine) every day to lower the prolactin level.
So jm pls don't waste time, check your blood to find out any hormone abnormal, it doesn't cost you much!
