Missed period.. with some spotting or implantation bleeding i think

Amanda 🍑

Okay so I had my period the end of last month like 24-28th. Me an my husband had unprotected sex during that time (while I was on the pill) we then had unprotected sex the 8th of this month. I had gone off the pill that morning, the next day I had some light spotting on the 9th an 10th. My period was due this Monday but I haven't gotten it yet, I'm 4 days late.. (I'm never late). I took a test this morning an it was negative.. but I still don't feel like I'm getting my period. I have had headache's the past couple days, an been bloated. Could it just be too early for the test? Or is it just going off the pill?
