What to do??

Sooo hey y'all

My period is still a no show for this month of January

I've been having cramps on my left side of and on for the past few days

Always eating/snacking(but that's nothing new to me)

My BF has been throwing up and eating weird things like a peeled orange with salt and pepper on it SMDH.

I took a test this morning and it came back negative

My cycle was supposed to be due on the 9th and still nothing

I also had a very weird and short 1-2 day cycle last month(which is unusual for me)

Seeking advice please
