Hi, I have done IUI just this current month, my  last month menstrual date is 11/5/2018 and as such now my date may be 11 ,12 or next days. But now i am having severe backpain. Does it mean that i am going to menstruation this month and abstained from pregnancy.. does the backpain means  my IUI is unsucessful. Can i take paracetamol or other cold related medicines after IUI. Please suggest.
