I give up

AF due today no sign of it. 14 DPO and constant BFN I tracked my ovulation and never have I had such a strong OPK before in my life but it was pointless as once again still nothing! I just want my rainbow baby 😭😭😭😭 6 months since my miscarriage and 15 months TTC my first I can’t cope with the heartbreak anymore. Maybe I’m just not meant to be a mum.
