I was 8 days late on my period, on the 5th day I had sore breasts I couldn’t even touch and they are still tender, on the 7th day I started cramping in my lower abdominal section and then had some white milky discharge, starting that night after sex I started to lightly bleed and I’ve now been lightly bleeding for a day

What’s going on and could I still be pregnant?

Please help
