I am 28 yrs old, married since 5 yrs. Recently me and my hubby planned to have baby. My first day of periods was on the 26th Jan 2010. We had sex on 9th - 14th every day. Now i have tenderness in the breast, heartburn, dizziness, tiredness, sudden sweating, a chill feeling, i feel like just sitting down, today i had loose motion, at times i feel nusea, no sleep in the night, lost apetite. Am i pregnant? Today is the 25 day of the cycle and i have a 28 day cycle. Can you suggest me the best date when i can take a pregnancy test, if you think i could be pregnancy.

### output:

Hallow Dear, Since your menstrual cycle is of 28 days, you had menses on 26th January, the period between 9th and 14th February is a highly fertile period for you. The egg release (ovulation) happens 14 days prior to next expected period. The egg has life of 24 hours while the sperms are active for 72 hours. Hence, your intercourse falls in the fertile period. It gives a good possibility of pregnancy. However, the first cardinal symptom of the pregnancy is missed period. You are yet to miss your period. All other cardinal symptoms; i.e. nausea & vomiting, frequent urination and breast symptoms like engorgement with tenderness, dark discoloration of nipples & areola with areolar widening, Montgomery's tubercles under areola and secretions from the nipples appear about 10-15 days after missed period. Home pregnancy test on urine should be performed on overnight first morning urine sample 8 days after missed period. Earlier, these tests may give false negative tests. You are yet to miss your period. So HPT done at this time may buy misguiding. Wait for your period. If you miss the period, then perform this test after a week. Alternatively, you may opt for Beta Chat Doctor test. These are very sensitive and specific tests and give reliable results even few days before missing a period. I wish you all the best luck for your motherhood.
