I'm hoping I've got Implantation bleeding!! I think I had it in January when I got my first BFP at 4 weeks, but then M/C'd at 5 weeks. I had brown spotting about 10 dpo. I'm now either 17 dpo or 10 dpo (not sure as cycles change between 21 and 28 days and sometimes I O about CD9 and sometimes CD14). Have had all BFN so far, but today brown spotting has started. I'm just praying for a BFP and a sticky bean!!
