16dpo and bfn?! Symptoms?

[AceSky]

I've been using fertility friend to track my cycle. I'm now 16dpo and elevated temps but I have taken numerous tests and for bfn! I've had lots of cm, constiptation, headaches, bloated and lower back pain! I have no idea what's going on

How regular are you? If you are normally regular and you are now outside that window, you could be. HPT aren't always that accurate. Symptom spotting my not help, every woman is different. I would wait til you are about a week late and call your OBGYN, ask her or him.

I hope you are! Best of luck.
