Answer 1

I sorry but those are all side effects of the meds

Answer 2

Home pregnancy tests are over 99per cent accurate when used correctly, so your doctor is right to suggest them first.  

Clomid doesn't always make women ovulate, and that would be my guess, that you had an anovulatory cycle and therefore your period hasn't come. All the symptoms you mentioned can be symptoms of PMS, Clomid, or a hormone imbalance. I'm sorry, I know this isn't what you want to hear, but I really don't think based on the info that you are pregnant.  

Answer 3

Clomid produces long cycles.  It is possible that you are pregnant and hcg isn't detected yet because it is too early.  On clomid I did not ovulate till day 26, and my usual day was 18.

Neither clomid or metformin will affect a pregnancy test.
