Help?!

Okay heres the weird thing. My period came 3 days early. Its normally heavy and bright red. And lasts 5-7 days. However this time it came 3 days early and was superrr light like almost didnt even need a pad. Like a liner wouldve worked. It was dark brown. And lasted 2 1/2 days. Then it completely went away. Now i have severe acne breakouts and this odd craving for cucumbers. Normally my boobs are sore during my period however this time they werent and i had no cramping.

We have been trying to conceive for 3 yrs. anyone had anything similar?
