Been puking for four days and wild mood swings 😭

Im supposed to ovulate tomorrow but we've been having sex since the last day of my period. I've been having the worst nausea ever and I have puked four times in the last four days normally 15-20 minutes after I eat. Could this be an early sign. The last time i puked was after my partner and I did the deed. I can't take a test for another week or two... I cant be crazy... Ive also had sore tender boobs, been very tired, lots of headaches and my mood swings are not being enjoyed by anyone😭😭😭
