What is the colour and quantity of bleed that you are having?
Post abortion, spotting can be expected for upto 2 weeks. If it is dark brown or blacking discharge, then it means old blood that is being expelled. No need to worry.
If it is red in colour, and just spots, you can wait and watch. Again could be left over tissue coming out. No need to worry right away.
If it is red and in large quantity, then you'll need to see your doctor to rule out incomplete abortion.
As per US report, she seems to be having polycystic ovaries, it is a common problem and it is too early to say that she will have any problem in conceiving. Prolonged periods soon after marriage can be due to stress. Irregularity in periods does happens in many girls for few months after marriage. If she doesnot conceive after trying for 5-6 months, get her honmones tested.
The medical abortion is done with hormonal pills... Which has effects like these... Especially irregular menses...
It should become normal gradually after 2-3 periods if you take no further hormonal tablets..
If it doesn't then take Homoeopathic treatment..
