IB or period I am really concerned and confused

Tahlia β€’

So yesterday afternoon I was getting mild cramps kinda like period cramps but no blood and today I have red blood on my pad but not heavy at all and I have been taking home pregnancy tests for a week now and they all have faint lines on them and I have been to the doctor for a BT and came back negative I have to go in today for my 3 results of my BT but I keep thinking that it’s my period but I am late for them so I am so confused πŸ˜’πŸ™ŠπŸ™Š
