i need help!

well this cycle i am definitely experiencing more things than a normal month, im not sure if they could be related to pregnancy though! i need help!! i can smell everything in the dang house, something that is in the kitchen while im in our room with the door closed. my teeth are super sensitive to the point i couldn’t eat much last night. i’ve had some morning sickness, i feel like im always freaking nauseous! my nails are growing like crazy, ive always been a nail biter so they would never get the chance to grow but now it seems like they won’t stop!
