Preggo???

july

10 days since I last had sex, then 6 days before that ,then 5 days before.... Not sure exactly when I ovulated as we've kinda given up trying. But my period is due today. No sign of it.

I haven't had any symptoms of even pregnancy apart from being really moody and craving prawns and tuna (????)

Are these indicators of pregnancy or am I getting my hopes up???
