Help please!

Hey ladies, so my period was due to start 4 days ago; over the past 3-4 days I’ve been having period cramps but not as bad, my skin hasn’t broke out like it usually does, I’m peeing like every hour which is highly unusual for me (I’m putting it down to a UTI), I get so hungry I feel physically sick but sometimes I do get a small wave of nausea, I’m getting like small pains in my actual stomach, almost like small stabbing pains. My boobs seem fairly normal? I haven’t done a pregnancy test but with times like these I don’t want to be wasting my money on stupid amounts, clearly looking for some advice!

I’m not trying to conceive as my partner and I haven’t been together that long!

Just wondering if anyone else has had something similar and what was their result?
