I'd be grateful if anyone could give me any advice. I'm 33 and have been trying for my third baby for three months (fell pregnant the first month of trying with first two). I know ovulated late in my cycle (day 15 of 25 day cycle) and definitely thought I was pregnant as had strong implantation pains a few days later just like I did with my two boys. Yet My period was due yesterday and hasn't come, despite having cramps on and off for several days. I could swear I was pregnant but have done two tests and they are both negative. I'm wondering if I might not get a positive result till a bit later if I ovulated late. Does anyone have any experience of this? I'm driving myself mad! Thanks
