DPO symptoms

Jenny • TTC #1
So I am 7dpo. Since the day after ovulation, I've had so much phlegm from my nose. I'm not sick. I'm not having any allergies. I just have a ton of nose mucus. I've also had a super dry throat and have been constantly thirsty. Today, I've had some pain on my left side. Hoping it's implantation cramps, but I haven't had any cervical mucus since ovulating. Any other ladies have similar symptoms and end up pregnant. I'm trying so hard not to test until AF next week.
