Ok ladies implantation maybe or bc period is next week?

Ok first I'm on BC and not TTC at the moment. I've been on antibiotics twice in the last two months and I may have been late taking some pills or even missed one til the next day when I realized and took it. I've been eating a lot the past month and have had a few dizzy spells and a lower/middle back burning pain sensation a few times last week. Ok well normally exactly a week before my period would come I'd get some very light brown discharge, almost every month this would always happen. Btw my last period was March 30 and looked as it usually does which is light and dark colored. Anyways, but this month I've gotten an orangish/pink discharge two weeks before my period that lasted a couple days and now, a week before my period I wipe and see this! Like I said, usually it's light and it's darkly colored every month the exact week before my period and lasts a couple days and goes away before my actual period starts. I've tested twice already last week and it was negative. Maybe I'm over thinking this? Something just feels a little off with me that's why I started thinking its a possible pregnancy but who knows. Any ideas?
