Started my period after a 40 day cycle today (had been convinced I must be pregnant as always 28 days usually), so now onto cycle 16 ttc and found out my partners sister is pregnant. Ended up having a bit of a breakdown at work and feel so selfish. Haven’t shown my partner I’m upset as he’s very excited to be an uncle, but I feel like such a bitch. Who cries over someone else’s happy moment?? I just feel so empty
