Cramping on lower left side at 5 weeks pregnant

Kristen

So I had sex this morning, and since then I've been cramping on my lower left side. It's not an unbearable pain, but it's annoying and hasn't gone away all day. I'm not bleeding, but I feel I should also mention that after being dizzy only for only two days after I found out, I have also had virtually no symptoms of being pregnant except for a little nipple tenderness. I was wondering if anyone else has dealt with anything similar? I'm just really looking for reassurance because I don't have my first appointment until Aug 9th.
