Am I just imagining things ?

So I've been TTC for a few months now and I feel like this is my month lol, I'm supposed to get my period tomorrow but my breasts usually get really tender and painful and this time they did not, I've also felt dizzy while sitting down . Maybe I'm just reading too much into this and I should know for sure soon but I wanted to get some feedback from someone who has been pregnant before ,could my symptoms be a sign? My MIL says the my breasts are supposed to feel even worse and I should have morning sickness, I guess she would know since shes had 3 kids but I also feel like not all women and pregnancies are the same .
