Cycle confusion.. help!!😣

My husband and I are TTC so i downloaded this app and LOVE it! However, im a little confused with my cycle, maybe you ladies can help me! So usually i get my period around the 20th every month but this month it came on the 10th. Would i have ovulated already or will it come at my normal time since my period was early this month! I have been SO crampy and tired since ovulating and sex on the 26th.. could that be early symptoms or is that just way too early? Sorry if i wrote this confusing! Im pretty confused myself and maybe just so excited im over thinking it!! Thanks ladies!❤
