Hello dear,
I understand your concern.
In my opinion there might be no chance of
pregnancy.
As per your information you were sexually active between June 29 to July 11.
And after that you had normal periods between July 29 to 31.
And once period occurs the chances of pregnancy are ruled out.
And after the period you were not sexually active to raise the suspicion of pregnancy.
But as a benefit of doubt the urine pregnancy test was done and it is also negative.
So there might be nil chances of pregnancy.
And the abnormal spotting in this period might be due to
hormonal imbalance.
This spotting might consequently get converted into periods or stop.
I suggest you to observe for the periods in next 1 or 2 months and if same abnormal spotting continues then I suggest you to se a doctor to rule out any
thyroid abnormalities or
PCOD etc.
Avoid
stress as it might also cause hormonal imbalance and cause irregular period.
Hope this helps.
Best regards....Dr.Srilatha
