So I got positive OPKs on the 4th/5th January. I'm due AF anytime between 17th-19th. I have had a bad back and felt sick a few mornings and maybe a bit more tired (but we are on holiday so might just be all the walking!) I have had 2 miscarriages, one natural (Aug) and one D&C; (Nov) and had a strange period in December after the surgery. I have just been to the toilet and wiped some light coloured blood. I had this last month before AF showed up then kinda went again and then came back over 3 days. I was just wondering if it could maybe be implantation bleeding and if I could test in the morning? Has anybody else experienced this? x
