Need help and advice please

JustMe • Im a mommy of a little girl who holds my world 💜💚❤
We has sex on the 5th my periods due on the 19th. Ive been getting this sea sick feeling every now and then the past 3 . Also if i dont take my time to stand i get dizzy enough to were my eyes go blurry for a few seconds. Today ive been noticing a slight cramping sensation by my pelvic bone which ive never felt before. Idk if im pregnant or if im just overwhelmed with ttc. Has anybody went through this or can anybody give me an opinion. I still have 9 days till my period. But id love if it decided not to come!
