AF due today and it's a no show

Kate
DPO 14 today, had very prominent early pregnancy symptoms the past two weeks so I'm feeling hopeful. Tested yesterday morning and it was a bfn, periods are like clockwork on a 27 day cycle and AF hasn't shown today which is strange for me. I never get sore boobs or cramps as normal PMS symptoms so to experience them this past week has made me wonder what is going on. Is it worth testing again even though I got a bfn yesterday? Also I've only got a clear blue plus test in my cupboard and I've read loads that they're not the best 😔
