16dpo and bfn but symptomatic!?

So I'm 16dpo today, had a faint line on 14dpo on a cheapo did a clearblue today nothing. But I've been getting hot flushes like mad, extreme hunger and thirst.

Tingly boobs but CM is pretty much none existant. AF due yestersay and usually get the start of it the day before. A few mild cramps today bit nothing.

What do we think? Test again in a few days of she doesn't show herself?

I'm chewing my nails off! Had a little boy in 2022 from IUI after 3rd attempt. This will be our 9th attempt this time round and I'm 38 now. I'm just looking for some good luck I think girlie's. 🤞🤞🤞
