No they are usually spot on unless I conceived and it has issues planting or w/e then I tend to be a bit late. Last time I implanted and mc I was a week late. Tested this morning with an FRER but I was heavily diluted, I saw a shadow but it looks like either and evap or indent. I'm starting to have lots of cm now but strange thing is it's creamyish not clear and watery. Having the pre AF cramps though just starting to kick in, so I probably will be spotting in a day or two. I think I'm gonna try and see someone about what's going on with me. I think it's time to see what needs to be fixed, before I lose all hope and desire to even try.
