Welcome to Health care magic forum.
In a delay of 8 days, one may not get the result, any how you can repeat after one week again. Do the test with the early morning sample of urine.
I advise you to have a trans veginal
ultrasound scanning. It should have
yolk sac and hear beat to confirm the
pregnancy.
If it is negative dont get nervous , you can conceive next month.
The symptoms may be coincidence, and may not be related to the conception.
I advise you that both the partners should consult the doctor for conception, to exclude
male infertility.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods, to make your systems healthy.
Wishing for a quick and complete recovery.
