Thanks for your health query.
All the symptoms you mention are not reliable for pregnancy
ALso, spotting in itself is not a sign of early pregnancy.
If she was on her pill, chances of pregnancy are quite low.
SPotting might be due to stress, weight gain, thyroid
problems, endometrial hyperplasia
, a polyp, polycystic ovaries
Please take a pregnancy test to know for sure.
It is a simple procedure and there is no point speculating when you can have a reliable, objective result in hand.
If the result is negative, repeat the conventional HPT once she misses her proper period.
ALl the best.
