Nauseous

So my husband and I have been ttc #2 this week but my period should be coming anytime. I had vaginal pain 2 days ago with bloating, yesterday I had bloating and very light cramps in my lower stomach. Today I feel bloated and I have been nauseous feeling. I have very irregular periods and we have done it every night this week and twice last night. What do y’all think? Could it be just my period coming?
