Thanks for the query to H.C.M. Forum.
If I were your treating doctor for this irregular bleeding and amenorrhea
I would come up with these possibilities, these includes.
1 Due to very young age group may be pcod
case , diagnosis can be confirmed by ultrasound
of both ovaries .
2 May be pregnancy
, as you mentioned that all symptoms are like that of previous pregnancy. Can be confirmed by blood for hcg
level and again one more home pregnancy yest.
In my opinion consult a gynecologist and physical as well clinical & history of illness will find out the exact cause.
Good luck. Dr. HET
