Ttc and confusing cycle?

We have been trying to concieve for 7 months and unfortunately have had 2 miscarriages allvery early one at 5 weeks and second at 6 weeks. I am very confused with this months cycle.my periods are between 29 days long to approximate 32 days long. Last period started 29th dec a normal period. A positive ovulation test 9th jan however I started bleeding late onthe 10th jan. It was dark brown blood and extremely light. Bleeding lasting 3 days no change in it at all. From what I have read to Internet implantion bleeding happens 6-12 after ovulation so what I was having mustn't have been implantation bleeding. Can any explain whether it is poss to have implantation bleeding this early? I then stopped bleeding for 1day and then today started again. Really dark brown no cramps very light. I am really confused whether I have been blessed with another chance or whether I'm just holding out for hope. ( I am completely heathy, no infections down there sorry if tmi )
