Question

Would I get even a slight positive hpt if I’m 7 almost 8 dpo? I’m having creamy white discharge with no odor and I’ve had it for about 4 or 5 days. It’s mostly in my underwear but a lot when I wipe. I had cramping several days ago and bloated so bad but no positive test yet. And my breast are slightly sore. Someone said that I would get a positive as soon as I noticed the discharge but I haven’t gotten a positive. Someone else told me to test 8-10 dpo. What should I do? Should I go ahead and test or wait for a couple more days. I’ve seen people get positives this soon just don’t want to waste a hpt because it’s the last one I’m buying unless my period comes.
