sorry to hear of your situation chick, if it helps i will gives you my dates, i ovulated 7th september, implantation would have been from 9-11th ish, i am due by my calendar 31st may but the midwife is working it out as 2nd june due to the 2ish days to implant as my ov bleed was on the 7th sept and could have been an extra day to release the egg. thing is it isnt an exact science as can take up to a week/ten days to implant.
i got a proper fat bfp on 26th sept which i would be about 18dpo
