Signs!???

Trace • I have a 18 y.o. Boy. 13 y.o. Girl. Ttc since 2015. Miscarried Mar 2016/May 2018/Oct 2019/Apr 2020/Apr 2021/Nov 2021/Aug 2022/Dec 2022/May 2023. Ttc our 🌈 baby.
Ok so I'm only 4 dpo. I've been getting slight cramping on and off. Constantly light headed especially when I get up quick or move quick. Randomly became a morning person which is so not me lol. But now today for no reason at all I feel tired and sluggish. Last night seemed like every time I ate I felt kinda yukie. Just curious if maybe this could be some symptoms starting? With my other two  children I was very sensitive to my hormones and extremely sick the whole time. It's been 5 years since I've had a babe so I'm rusty lol. Tia.
