I'm ttc and am on Clomid as I have PCOS...(but am slim and healthy) .... I had loads of early pregnancy symptoms over the last week or so but was gutted when I believed my period had come. However it was only brown blood and lasted one heavy-ish day and barely anything past that. I ovulated around day 18 or 19 and the bleed happened about 12 days after that. I've taken an hpt yesterday (the day after the reasonably substantial bleed) and it was negative. Why was my bleed so short and dark? Is it possible it was a late implantation... (Hence why bfn on the hpt?) Also I had two healthy eggs this cycle, so would the implantation bleeding possibly be more when it is two eggs trying to implant? So many questions but look forward to your thoughts....
