Pregnancy

I have been trying to get pregnant these past three months. But no luck. I just had relations this last Friday and it’s way too soon to take a test. But I have never felt this tired and I get random cramps near my vagina. Not regular period cramps. Is this normal? Any signs at all?? It’s now 5 days since last relation with my partner and my period is not due until exactly two weeks from now according to eve.

Any suggestions or advise? Truly not sure why I’m feeling this way but I feel it’s too soon, so just a tad bit scared this isn’t normal?
