Super sick, is it mono?

So for about the last month I've been really really sick..
I missed 3 days of school lastweek and I missed two this week..
I cant help that im sick.. Like right now im still really sick and I dont want to go to school tomorrow but should I?
And why...

would I be so sick? Not like throwing up everyday sick .. Like feel like throwing up, sometimes I do.. But I feel like I have the flu but I dont know why it would be such a long time..
My friend said it might be mono

if youve had sex you could be pregnant & be having morning sickness you should take a pregnancy test

I've been sick for a little over a year and have many health problems and I missed a lot of school too my opinion is to go to the doctor until they figure out whats wrong with you and I wouldnt go to school if I were you cause you dont know if you could pass it on to someone else. and I dont know where about you live but where I live there is a bad stomach virus going around with some flu like symptoms without the major ones
hope it helps

go to the docters & ask
but if it's just a cold then there's what you do
boil a cup of water
add into it 2 tbs of chamomile
2 tbs mint
1 tbs garlic
1 tbs onion
large pinch of pepper
3 tbs(or more if you like) of honey
1 tbs of sage
mix it well & drink up

it's nasty as hell, I usually have to write a warning on it to whom ever I recommend it's so nasty
try drinking it through a straw or, only if you know you have the stomach for it, chug it down as quickly as possible) You don't have to drink it all at once, just drink at least a cup before it gets cold, basically within an hour period.
It is so nasty, but it cures me within 2 days, every one else whose tried it was cured within a day, & you can feel it work almopst immedatly.

its not a pregnancy thing lol
