Did anyone just 'know'?

Nicola • I`m a 32 year old teacher from the UK. Had my rainbow baby in September 2017 after miscarrying twice. Had a chemical pregnancy in January and now TTC #2
Been TTC #1 for 6 months now but this month I just feel different. I don't know why, but I am sure this is my month. I've been sure before, but not like this... Just wondered if there are any success stories like this? Or am I just imagining things? X
