HI! I had my prostap injection on Wednesday and I'm wondering if anyone can tell me how long after their injection they had a bleed? My next appointment is on the 10/5 and I am supposed to have a bleed in between. When I go back they will check the lining of my woumb and if nice and thin I can start stimming. I'm just worried cause so far there is not even a hint of my period starting. Usually I would have started spotting by now. I have a bad issue of spotting for a week before my period!
