Hello, I am 26 years old and we had intercourse on 21st feb17. My last period date was 8thfeb. My cycle is regular 28-29 days. I have no periods as of now.
I have headache which last sometimes for 5-10 minutes or sometimes longer than that for last 5to6 days. I have periods like cramps for last 3-4 days but frequency is less and pain is also low.
Today I have done home
pregnancy test and it is negative. What could be possible reason for headache? Is this type of headache an early symptom of pregnancy?
