Late every month all of a sudden for the past 3 months

28/3/19 👼💔Mummy to a beautiful girl 17/08/2021💗

We have been trying for 7 months now and only since 3 months ago my period has been irregular.... I have always been regular. I cant stop feeling so agitated when I get my period. I'm 2 days late now again and it's just playing with my head and emotions. I'm 26 and my partner is 41.
