Hello dear,
I understand your concern.
In my opinion the withdrawal method is one of the natural method of contraceptions.
The first sign of
pregnancy is missed period.
The other symptoms of pregnancy are
nausea,
vomiting,increased urination,sore breasts which start 2 weeks after missed period.
As per your history there are rare chances of pregnancy as the withdrawal method was used.
But confirmation is done by urine pregnancy test.
The urine pregnancy test is done a week after missed period (if at all there is missed period)for accurate results.
If the test is done befor the said period I suggest you to repeat the test.
If the repeat test is negative then the is no chance of pregnancy.
So in that case wait for spontaneous onset of periods for 10-15 days.
If still no period I would like to see the doctor for medicines for withdrawal bleeding.
Avoid
stress regarding the thought of pregnancy as it itself cause
hormonal imbalance and might delay the period further.
Hope this helps.
Best regards...Dr.Srilatha
