TTC 2 weeks late negative hpt no symptoms

Hi, I’m 33yo, with high BMI and I am 7weeks since first day of my last period, 4 weeks past day of ovulation. Had sex on ovulation day, and have tested twice last week and once yesterday and still negative result. I’m experiencing some vaginal dryness but my cervix seems high. I have some indigestion, feel bloated and joint pain and a little tired mid day. I’m not sure when I should call my ob to find out if I am pregnant. The hPT is negative but I’m finding that’s really rare if you actually are pregnant to get negative result. I feel like as soon as I call to make OB appointment I’ll get AF (Aunt flow). I feel almost like I have a gas bubble right above my public bone and I’ve been extra weepy. Do you think it’s possible I’m pregnant? Is it time to call the doctor or should I wait another week? Thanks for the suggestions.
