28 days late......2 periods missed!

Adele

So today I’ve officially missed 2 periods. This has never happened (apart from when I was pregnant 8 years ago). All tests negative, I last tested over a week ago. I haven’t been stressed, it’s been kinda nice not to have a period. We have been TTC for over a year. I suppose next step is a trip to the GP. Should I test again before I go??
