HI, thanks for using healthcare magic
Pregnancy tests check for the
HCG hormone. In a pregnant female the levels of this hormone increase as the pregnancy progresses.
It is normally detectable by most home
pregnancy tests by day 11 to `14 after conception.
If you would have passed this time period and the test is negative then the result is likely accurate.
It is possible that your symptoms are premenstrual symptoms.
Women can experience physical and emotional changes leading up to the period.
The intensity can vary.In some women the symptoms can be severe.
In severe cases it can be treated by different methods including
counselling, dietary changes and medication.
If these symptoms occur before your next period and are intolerable, you may consider visiting your doctor for an assessment.
I hope this helps
