Hello dear,
I understand your concern.
In my opinion there is no chance for
pregnancy to occur 6 weeks after intercourse.
Once you get the period there is no chance of pregnancy unless you have
unprotected intercourse after the periods.
As nothing such happened and the last intercourse was done only on November 14th after which you got the periods the chances of pregnancy are very rare.
But just as a benefit of doubt a urine pregnancy test can be done to rule out the pregnancy.It will be positive from one week after the missed period in case of pregnancy.
And by 3 months of pregnancy physical examination also helps in diagnosis.
I suggest you to
consult doctor for further work up.
If there was any pregnancy the symptoms like
nausea,vomitings, increased urination,sore breasts would be present as all the symptoms start around 6 weeks.
But overall the pregnancy appears to be rare or nil possibility because you got the periods and you don't have any symptoms of pregnancy.
So relax.Avoid stress.The delay could be due to
hormonal imbalance as the birth control pills were stopped.
Avoid stress as it also delays the period.
Hope this helps.
Best regards.,.Dr.Srilatha
