Concerned need advice

I've been TTC for 6 months now and recently  for the past month or so when the app says I'm ovulating we try everyday then right after I get a rose you pink hue discharge then brown the next day which I think it's implantation bleeding then get a full blown period 😓 I don't know if this is the right place to put this but is this normal? It's makes me feel like I can't have kids 😕
