HELP! ttc, late period, clear/stretchy cm instead of period

Sorry if it’s long but i just need advice. Hubby and i decided to try for baby #2 in march. So early march i stopped taking the pill. AF arrived every month except for July. When AF would come sometimes it was light and short and wouldn’t get here on the day it was supposed to. Maybe like a day 2 late. I have different period apps and they’re all different. according to glow and flo im 19 days late. according to ovia and period lite im only 15 days late. I took a pregnancy test on july 28th and came back negative. Haven’t tested since then. The thing here is im positive i ovulated in the month of july when i was supposed to. i had the egg white cm, pelvic pain and sore breasts. And since the day i was supposed to get AF it’s only been clear/stretchy cm and even pelvic pain a few days ago. With my first baby i was only 5 days late when i tested and got the positive result right away. Only reason i tested with my first pregnancy was because i missed my period and had heartburn. this time i have no other pregnancy symptom just the missed period. Has anyone else gone through this and got their BFP later than they did with their first pregnancy?? im afraid to test again and get a bfn. im just so frustrated if i’m not pregnant i want for AF to get here so we can keep trying 😔
