I'm 33 years old married. Been trying to conceive for the past year, no luck. I used an app to track my cycle to know the exact day and we did it on that day last month. I never missed my period ever. This month, I'm already 5 days late. I have slight cramps, fatigue, a small amount of white discharge and headaches. Tests show negative, I took the last one yesterday. Body temperature is 99.32F.
Could I be pregnant?
