Hi there, I have understood your concern and I will suggest you the best possible treatment options.
First of all do not panic.
I will suggest that she should get gynecology check up done including per speculum and per vaginal examination done. This will help to know about any cervical erosion or polyp as a cause of her bleeding..
Secondly, if you are trying for conception, I will suggest that she should opt for a healthy diet and regular exercise regimen. Start on
Folic acid and vitamin B 12 supplements regularly,this helps to prevent various complications during conception,
pregnancy and delivery.
Also, you might be aware that in a woman with regular cycle day 10 to 20 of the cycle is the most fertile period of cycle. If you have unprotected sex activity in this period at least on alternate days, it helps to get pregnant.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar.
