Need help and advice

Ja

so I am now 28 days late now.. around the 25th July I had some weird brown bleeding.. it was next to nothing but had little stretchy clots.. that lasted a week with a little cramping and when I read about it everything was saying that was implantation bleeding.. so it's now been over 2 weeks since that stopped and pregnancy tests still negative.. been trying to conceive for 20 months now.. any one got any help or advice for me? 😔😔
