Hallow Dear,
You seem to be quite confused about the signs and symptoms of
pregnancy. Running nose, fluttery sensation in the abdomen, bloated feeling or fatigue are not the symptoms for early pregnancy.
Missing a period is the cardinal symptom of pregnancy which may be associated with nausea and
vomiting, frequency of urination and breast signs which include engorgement, tenderness, darkening of nipples & areola with increase in areolar size and secretions from the nipples.
The period you had was doubtful. Brownish spotting with a tissue does not support the
menstruation but suggests
abortion.
If it is more than a week that you have missed your period, you can do either urine pregnancy test or
ultrasonography to confirm the diagnosis. If it was an abortion, the urine pregnancy test will not be of use; better go for ultrasonography. If the abortion is incomplete (which is very unlikely at this stage), you may have to get it completed.
Please report to your Obstetrician for further management.
I hope you have got the proper guidance.
