Is it normal to have lights spotting period That only lasts 3 to 4 days  

I feel like it's a  big issue that could be one off The reason why I am not conceding. 

It only started after I had my son I had a C-section because The baby was too big and they gave me two reasons why I should have a C-section 

One if I give birth naturally The baby could die and two I could get paralysed. i've been trying to conceive for l two years now
