Idk what to think anymore

I’ve been getting faint lines but it’s been 2-3 days and isn’t getting darker. Not sure if I am still early.. I start my cycle in 6 days.. or so. I called my doctor this morning and hopefully hear back. I’m getting faint pink lines. So idk what to think. Slight cramping for about 4-5 days now, constipation, blushing on cheeks (feel hot) and my BBT has been 99.1-99.5
