Waiting..

I wrote a post last week, i finished my period on a friday and exactly a week later i had a 3 day light bleed, i was due on my period friday just gone 08/12 and have yet come on, i have done 3 tests and all negative, im having strange cramps and sore boobs and shoulder pains, has anyone else been like this before, and if so what was the outcome ? Me and my boyfriend have been trying for a while now so would be so excited if this a good sign! Thank you guyss x
