Don’t want to get my hopes up 😅

Hi!!! So I am currently 5 DPO (I know it’s early) and we had sex the day after the app said I ovulated. For the past 3 days in a row my breasts/nipples have hurt pretty bad and yesterday I was having crazy hot flashes, cramps, and fatigue. I felt a slight sharp pain in my lower pelvic area too. I looked back into my past logged symptoms after I have ovulated and have not logged anything at all similar to what I am experiencing now. The only time my boobs hurt are literally the day before my period starts. Could these be pregnancy symptoms? I don’t want to make my self crazy. These just aren’t normal symptoms for me after ovulation. Thank you!!!
