What the actual hell is going on? (No pics but may be slightly tmi)

Okay. This may be a long story but please bear with me. I have two kids. Always had regular periods and have been on birth control pill since I was 16 minus the pregnancies (got pregnant due to missing pills).

Anyways I have taken the pill religiously since my son was born May 2016. Had a normal regular flow period every month. Always would get my period by the Wednesday after finished pills. All was great until May.

Mays period came late on the Friday after finishing pills and was extremely light and pretty much only noticed it when I went to bathroom. Last months period was on time and a bit more closer to normal. Still somewhat lighter though but heavier than May.

Well I'm not due for my period until Wednesday July 12 (last pill taken Saturday night). This morning I woke up to pee and when I wiped there was super light pink/clear, almost barely noticeable discharge. So I was like ok this is weird. It's never come on the Monday before. So I put a pad on and went about my day. By now if it's my period it should be getting a bit heavier. Still super light pink/clear discharge only when I wipe. Nothing on the pad.

I'm on birth control pill like I mentioned so up until May periods have been like clockwork. Had sex June 30 but again, on the pill.

This can't be implantation bleeding right? Or could it? I'm just so confused :( Any insight would be greatly appreciated and thank you for taking the time to read my rant😆
