Why do i get all the pregnancy symptoms but in the end i end up getting my period?

Be more specific: Which symptoms specifically? Some may just be associated with the second half of your cycle or could be another hormonal issue. Best to check with your obgyn for more details. Good luck!

Pregnancy symptoms ?: The most accepted pregnancy symptom is lack of menses after intercourse. The rest overlap so many other conditions they are never considered reliable or exclusive to pregnancy. Some conceptions are shed before pregnancy is established, but the recognized symptoms are triggered by the chemicals created by the new pregnancy after it attaches to the womb making this a less likely explanation.
