PROM😱😣

Shannon
Hi everyone,
I've finished my GCSEs now and I've got my prom on Friday the 23rd of June. I check my app and calendar almost everyday and my due date for my period isn't until it 26th. 
I wake up his morning to find Mother Nature has visited early!!😭😫
I really don't know what to do as I've not tried out tampons before and I can't wear 'period pants' cause I'll get lines showing through my dress😩 
If anyone has any suggestions I'd actually love you forever cause I can't throw away such a stunning dress😅
Thank youuuuu💕
