How do i know if i have pms?!

How do i know if i have pms?

i was on the implanon for 1 year and i had it taken out because of servere wieght gain and it got me down at times. although i had the implant taken out i miss it because i never felt stressed and never suffered from what i think i have 'PMS' now i'm on cerrezette to help balance my hormones but i've been on this pill for 5 months and my periods are very irregular and i'm VERY stressed, always confussed what i'm thinking, always finding problems with my partner ( which i very much love) which he can't help and always deppressed about everything. i really want to get whatever this is cured because this isn't me and i don't want my bf to end up hating me i really love him and don't want to hurt him anymore! ( also i never no when my periods they come and go all the time). thanks to anyone who can help. xx
