Late with negative result

Tiffany

Hey there! Not really sure what I'm looking for maybe just someone to relate to haha. I'm 8 days late for AF, took a test 3 days ago that was negative. Only thing out of the norm that I've had is a splitting headache from time to time and the last day and a half feel like gassy almost? (Like a pressure feeling almost in my lower abdomen) no cramps and I'm always regular. Just irritating not knowing for sure I guess. I know tests are super accurate but I haven't been under any stress lately and can't think of any other reason to be late..Anyone else going thru this??
