Symptoms

Hi I'm not a 1st 2nd or 3rd time mommy by any means I've had 5 beautiful babies but my baby is 13!!! So it has been 13yrs since I've had pregnancy symptoms but me n my husband r trying for 1 more IF I am I would b 3weeks 3days would my breast start feeling sore right about now or is it too early??? I really don't remember how far along I would be when I would feel symptoms like sore breast or spotting or anything we never planned for any of our beautiful angels I would just miss a period or 2 and then take a test lol so this one is a little tricky to me it's different so every little thing's make me think oh mayb I am awww mayb I'm not... HELP lol
