the oddly fat calyx(es) and brown hair are not good signs this early... but, you'd have to pull one off and split it open... even that if too early might be too small to recognize a developing seed.
the long white pistils with no plump at base. are not pollinated. So, that's a good thing because it's not wide spread.
Scan over all your plants for herms. nanners are not a big deal, but entire pollen sacs are a big problem, especially if they are open..
