hello,
Chance of
pregnancy is high,if unprotected sexual intercourse is done with ejaculation around ovulation time in regular period. Ovulation occurs approx 14 days before due date.
In your case,you did unprotected sex around safe period (as per calculation your ovulation occurred on 7th Jan if next due date is 21st Jan). So chance of pregnancy is almost nil. It is better to wait for upcoming period and do a urine test for Beta-hcg after 1 wk of missed period to confirm/exclude pregnancy. Check the result and consult with doctor.
It is most probably associated with Pre Menstrual Syndrome (PMS). Do the following things:
1)Avoid salty food/coffee in 2nd half of period,
2)Avoid
stress by yoga/deep
breathing exercise.
3)Control body wt & Take healthy diet,Drink more water.
4) May need Tab
FLUOXETINE & OCP/
Progesterone pill.
5) Maintain personal hygiene and need proper sleep.
Be well and practice safe sex in future.
