Hi all. After some advice please. So I had my last period 4th September. Been trying through fertile period, didn’t put pressure on myself as didn’t expect to fall straight away as had a mmc in July. Anyway I just felt different in the last couple weeks, really heavy boobs again, strong metallic taste in mouth that I couldn’t ignore, lower back ache and drained feeling. Period due next week, but just today I’m now spotting like pink watery blood (sorry for tmi) not filling a pad though. Pressure feeling on ovaries no cramp though. Is this too late for implantation bleeding? X
