4dpo. Had prenatal OBGYN visit today

So I had planned this vosit to the OBGYN about a month ago when we decided to try to get pregnant. I'm 4dpo so a bit early to test. She did a pap smear test so I cant trust the pinkish discharge in the toilet paper. At least not for a couple of days. If it happens again in 2-3 days I'll definetly get excited. My husband is 100% sure I'm pregnant. He says I havent been myself for the past couple of days. I've explained to him tha even if we did fertilize an edd it coudn't have possibly implanted yet so there is no reaspn for me to be having any symptoms yet. I think I could be but I don't want to get my hopes too far up that I get way bummed if I'm not. I mean its only my first time TTC and yes we are both healthy and my cycle is like clockwork and my husband's sperm has weapons or something because he never used to finish inside and he's got two kids and I terminated a pregnancy early in our own relationship and he hadn't even finished inside. So I understand why he thinks I am pregnant. Plus yesterday I had flulike symptoms, I never eat junkfood or soda and last night I was drinking pepsi mixed with seven up and eating popcorn at 1am and I've been overly sentimental and I've been back amd forth between constipation amd diarrhea for the past 3 days. Anyway, the doctor talked to me for a while, she was super nice, I think if I'm pregnant I would want her to be my OB. Have any of you ever felt pregnant befor 5dpo?
