hi, we are into our first ivf cycle (1 little boy conceived naturally but Tubes blocked since), it all went very well, but 7 days after the embryo transfer I'm having some cramps and light spotting. It feels like a period but it would be too early, and I thought impossible on all the post-drugs. But I don't know really and was hoping someone might be able to say whether this means anything or is to be expected? Any knowledge or experience gratefully received! Thanks x
