I'm trying to get pregnant and my last "real" period was on 8/20. Had sex on the 29th and 9/1 hoping to catch an egg. Had wierd bleeding that started on the 12th of September, hoping it was implantation bleeding. But it lasted several days. Never really had a "real" period. I took a PT on 9/22 and it was negative! But last night I felt really sick and I've been feeling hot for the past couple of weeks. My husband asked if I was pregnant because he had "morning sickness" and all I could say was I don't know. Has anyone had pregnancy symptoms and a negative test at 18 DPO and still been pregnant??? HELP???
