Help!! 😩

Destiny • Waiting for our miracle. ❤️
I'm on cycle day 20 and have been waking up the past few days with excruciating head aches and dizziness and I've read that some ladies experience headaches in early pregnancy. Could I be experiencing them this soon? I just don't wanna take any heavy medication if I could be pregnant. If not, I'm definitely going to the doctor. Anything will be greatly appreciated ladies. Thank you.
