Help Me!

This is my first month TTC. I have not Been TTC in over 3 years due to a twin birth and with that being said I forgot everything! Lol!! 😂😂😂😂😂

Period is due in 7 days. I feel odd. I been feeling lightheaded/nauseous until I eat, lots of headaches, and I did have sore boobs but that went away and now I have tingling nipples at random times. Are these good TTC signs? I’m really not expecting to conceive right away but I like to keep the hope alive ❤️
