Possibly pregnant

Ali

So I’ve been having some symptoms and wanted to know what y’all think I get a test Sunday but I’m not entirely sure I’m pregnant I’ve been having extreme lower back pain nausea every morning I’m craving stuff but I don’t really have an appetite I can’t sleep unless I lay there for an hour, yesterday I cried about 20 times all together and I haven’t ovulated since I got off birth control December 5th I ovulated before December but it hasn’t happened yet I’m January. Any opinions? I’m 19 and this is my first.
