Dizzy and tired @ 11 dpo

Hey everyone. Last week I had really bad cramps at 7 dpo that went away and now today and yesterday I have been extremely tired and dizzy (to the point where I can barely get off the couch). I’m wondering if this is because my period is due in 3 days or if it’s possibly early pregnancy symptoms? I was going to wait and see if I got my period Friday before testing but if anyone thinks this could be early signs I’ll test sooner.

We had a miscarriage back in March and since then have been very casual about trying for another (trying not to get too excited about if it will happen or not so we don’t end up disappointed)
