Hello ladies hoping someone can help me, last month my cycle was 23 days and now I’m supposed to come on my period tomorrow which will make it 28 days this time so now I have no clue whether i have missed my period with it changing. I have no signs of my period coming tomorrow i just have a lot of discharge and sore boobs sorry tmi. Hoping someone can help and whether they’ve experienced this before , would really appreciate the advice
