still no baby 🙁

Kirstyn
For the past 2 weeks I've had constant stomach cramps, the worst I've possibly had. Always feel tired,constant headaches,backache and I always feel nauseas in the morning.
 I've took a pregnancy test today, 4 days before af is due and I'm not pregnant. 
My doctors told me to do another one at the end of the month and if it's still negative he wants me to go for a blood test,if I still carry on feeling the above symptoms. Praying for a baby so much!
