I experienced this since around 20 weeks, it comes and goes throughout till I deliver then it goes off completely. Ofc I also did blood test to rule out other possibilities to be sure it’s not caused by other factors. Do consult your gynae!
I experienced it too and even had Bppv toward the end of pregnancy. Do rest more and load on iron rich food. But nt too much too as it will cause constipation
