I'm in the same boat. I had spotting and CRAMPS on the 20th and 22nd. Really not sure what's going on with me right now because AF started on the 2nd and stayed for about 11 days! I called a RN on the 22nd because I've never had spotting or cramps between AF and it scared me. She said I could ovulate soon after my late AF bleeding stopped, and it sounds like the right time for implantation. I posted all of my symptoms in another thread. I'm soooo stressed out, waiting a few days to test. I hope you all get the results you're looking for.
