Overemotional ?

Flora
Hello girls !
I am an emotional wreck today. Tired and crying and I forced myself to stay in bed and read tonight. Can it be hormonal ? No LH surge this morning on OPK but just discovered EWCM tonite so I am confused ..
I am day 21 of my cycle. The last one lasted 45 days, the one before 56, they seem to be reducing.
Has it ever happened to you ?
