Was On Depo For 5 Years, Came Off Of It

Was on depo for 5 years, came off of it for about 5 months ago, my period wasn't regular for the first 2, but my last 2 months was a regular cycle of 24 days. If it's still going the regular cycle I'm 16 days late, doing "home made" pregnancy tests, not a negative, but not a positive. I done a sugar and urine test for a few days in a row, if your not pregnant the sugar dissolves, and if you are pregnant it is suppose to clump up. Well the first few days I done it, all the sugar dissolved, now the sugar isn't clumping, nor dissolving it just sits at the bottom of the bowl. I had many pregnancy symptoms before my missed period, now they're all gone except for I'm tired, having cramps, and sore/tender girls. For the last 2 days I've had some weird spotting going on that has never happened before, yesterday it was a very light creamy pink, and today it's very bright orange with an Undescribed weird smell. Period trying to get back on track, or pregnancy??? I'm on no BC whatsoever, and have been having unprotected sex using the pull out method. Please help. I turn 19 in a month, and just need to know if this is a weird "life change" going on with my body, or if it's possibly implantation bleeding. I was taking baths in Epsom salts, and I'm guessing when I leaned back to wash my hair some of the water entered my vagina, I haven't been wet like I usually am during intercourse. I also had a bad smell that I literally can't describe, all I know is I smelled it all the time for 2 days, baths didn't even help. Me and my partner switched condoms after we ran out for a while so idk if it could have been an older condom, that caused the smell, but now it's gone just having the new weird smell with the orange and light pink creamy nasty on toilet paper after I pee. Is this implantation bleeding, or my period? And let me add this is fuckin bullshit that I have to pay to ask a damn question. Thanks, this website is a ripoff.
