Please help

Has any had their tubes removed and gotten pregnant? I am 2 1/2 months postpartum. I had my first period after my c-section. My first period was a normal 7 day. It lasted from May 28th to April 4. I had my tubes removed back in February after my last baby. I dont know how this whole period thing works while having your tubes removed. Please no harsh comments. If it help any I am 27. Also to add I am not pumping or nursing. I didnt produce enough. This is also my third and final c-section. Thanks
