late/missed period?

[DannielleVictoria]

Good morning ladies!
For the last year or so I have been keeping a close eye on my periods and ovulation as my partner and I are trying to conceive. My periods are pretty regular and my cycles last around 27 to 30 days at the most.
The time my period was due to make a arrival (8th-11th) nothing was there, not even a slight sign of it being on its way! I'm now on day 34 of my cycle and decided to do a cheapo test yesterday and this morning but both tests came back negative.
For just under a week i have been experiencing a dull cramping sensation in my lower abdomen (but not regular) tiredness and my boobs are a lot more tender which is strange because i never get any PMS symptoms apart from a grumpy mood! Does anyone have any helpful advice as I'm feeling a little confused

I think it just comes down to waiting another 3-4 days and testing again or seeing if your period turns up. It's so frustrating!
