Cramping and light spotting?

RD

First time pregnant lady here… I’m just under 6 weeks and have been feeling twinges on the left side of my pelvis for about a week, and breast tenderness for a few weeks. I’ve taken 4 tests over a few days and the lines have progressively become lighter, like I can barely tell there’s 2 lines on my 4th test.

Today I wiped and there was a light pink tint and I’ve had some cramping on the left side. I’ve also lost the twinge sensation and no more breast tenderness.

Is this the start of a miscarriage you think? All thoughts welcome..
