2 days late

Been ttc for 4 months now and EVERYONE around me is getting pregnant. My sister even announced her pregnancy at the yearly family trip that I was hoping to be able to announce mine at. Even though they had been saying for a long time that they were done after their 2nd kid. Needless to say, I did not handle that well ...

Now I'm 2 days late and getting bfn's, and I really feel like my period's starting today or tomorrow. I am so bummed and am starting to lose hope. I know it's still early, but my mind is not accepting that haha.

I always have cramps during my tww, but this month's were different. My nipples are also super sore which is abnormal too, so even though I tried SO hard not to, I still got my hopes up.

Sorry for the long post, but I had to vent a little.

How long have people waited to test fertility? I know they say wait a year if you're younger, but it's still crossed my mind at this point.
