Too early?

I'm so confused... my husband and I have just started to not prevent... we had sex the day after I ovulated according to this app anyways my period was due Friday also according to this app. Usually I'm 1-2 days early. I've been testing every morning using the little hcg test strips all negative.... I have been having some light cramping but it doesn't feel like period cramps🤔 I'm trying not to over think this but it's hard not too! Guess this is kind of pointless to post but I'm just so anxious!
