Feeling strange ...?? 😳

Liddy
Morning all
I've woke up feeling strange today. I'm 9DPO and af due 18th but today I've got that feeling as though af is going to start.  Yesterday had very slight pink ting in my discharge/CM feel very mild cramps and just generally off. Really hoping my af isn't starting and early at that I'm regular at 28 days. Past two days had metallic taste not today at moment. Felt bit nauseus this morn and my appetite is slightly increase. 
Anyone else feel lol this? I'm probably fantasizing these feelings lol I'm confused Â
