Thanks for your query.
In the best of hands, IVF has a success rate ranging from 30 - 35 % percent, in absence of other factors like uterine fibroids, endometriosis
It is very common to experience slight bleeding / spotting / vaginal discharge
after embryo transfer
, as the endometrium and cervical canal is slightly handled.
please do not worry about it, as it does not affect your chances of pregnancy
If the bleeding increases, consult your doctor.
Mild pain is also common due to uterine cramping.
All the best with your cycle.
