Symptoms? I'm impatient

Kourtney
Okay here's the scoop.. I had sex and the condom broke on the 18th of September. My last period was September 9th and no sign of it now. Glow says it should be here on the 18th of October. I took a cheap test 4-5 days ago, negative. Took a cheap test today, negative. Symptoms I have- hot flashes, headache, mild backache, acne, hungry a lot, frequent peeing, and two nights ago I ate chicken nuggets with chocolate milk... Which normally I would think is gross. I got a little sick to my stomach today but only for a short time and I didn't vomit. I got a weird cramp yesterday when I bent over that didn't feel like a period cramp, but it was low by my uterus. I've also been pretty gassy and can't hold it in easy like I usually can. I get really tired doing simple tasks that don't usually get me tired.. And lastly, boobs are a little sore, and very itchy. What do you guys think?
