Thank you for your query.
Please consult your gynecologist at the earliest.
The darkish brown bleeding hints at an impending abortion.
The increased and fresh bleeding and discomfort means that it could be turning into an incomplete or a complete abortion.
You would require urgent re evaluation and if necessary a termination to ease the abortion.
If the pregnancy
is salvageable, you could require admission too for a few days.
Please go to the ER and do not take this lightly, as you could lose your pregnancy as well as have the ris of severe bleeding, infection, incomplete abortion
