HELP NEEDED! (Advice, Opinions)

I dont even know what to think.

March 16th -22nd was my last period (havent had one since), Ive been having painful cramps all over (back, stomach, sides), then I had what felt like a UTI, which I went to the doctor for and the test didnt show I had one.

Also, no sex drive at all, which is so weird!!!!

Could I be pregnant? I'm scared to take a home pregnancy test because I've had so many negatives!

Ive dream about being a mom since I could remember. I would be extremely excited! My boyfriend would be overjoyed.
