I have a 1 year old and over the last year we haven't used protection, resulting in 2 miscarriages (I suspected, 1 confirmed)

My last miscarriage was in early June, I've had 1 period since and AF was due 9 days ago.

I took a first response pregnancy test this afternoon and it was a BFN.

I'm starting to worry that I won't be able to have any more babies, I want a sibling for my daughter so badly!

Should I rule pregnancy out at this point in time or is there still a chance I could be pregnant?
