been 3 weeks with a 48 day cycle and I think I'm having symptoms.. 😥😥😥

So as you can see, I have a 48 day cycle, and it's been exactly 3 weeks today. I've been feeling really nauseous, one miniute I feel like vomiting and the next I feel completely fine? Is this normal? I also had tingly boobs but not so much in the nipples, maybe when you touch them.. is it too early to be having symptoms? I have no idea when I ovulate but me and my bf have been ttc😌anything is helpful💞xxxx
