I did my trigger shot on monday the 19, can someone help me out on when to test. I dont't know what to do. I had a negaative blood test last night in th ER, but from what i am hearing that is to soon to have correct answers. my period started on OCT 7, did chlomid days OCT 12-16 AND TRIGGER SHOT ON OCT 19. I am a very regular 28 day cycle, although last cycle my period came a day early. I have been having serious heart burn that i normally only get when PG, my breasts are still very sore. PLEASE HELP ME WITH YOUR ADVICE!!!
