Well on Dec the 1st we tried again with A Soft Cup (Instead Cup) . And the next day i started my period allll over again!! 😫😫 im crampin sumthin awful and my. Boobs r extremely heavy and nipple r kindve sensitive!!! Is all this a good sign?? Of course ive done research and ive readthat you   start your period thats how they calculate yur due date from the start of your last period! I just want some feed back! Cause i don want to be excited even tho its extremely early!
