Hello dear,
I understand your concern.
In my opinion the delayed
menstruation in a sexually active woman needs to rule out
pregnancy.
The delayed period with sore breasts first gives a suspicion of pregnancy.
But it is confirmed by doing a urine pregnancy test.
Usually a urine pregnancy test gives accurate results a week after missed period.
If you have done the test within the stipulated time above and the test is negative there might be no pregnancy.
But anyway I suggest you to repeat the test after a week.
If the repeat test is also negative then there might be no chance of pregnancy.
And the sore breasts might be a premenstrual symptom.
Then the delay in period can be considered due to
hormonal imbalance.
The hormonal imbalance might be due to
stress regarding pregnancy or anything.
So relax.Avoid stress.
If the test is negative wait for spontaneous onset of periods for a week or 10 days.
And if still there is no onset of period even then consult gynaecologist.
Nothing to worry as such.
Hope this helps.
Best regards....Dr.Srilatha
