😩😩😩😩😩

Period was due 4 days ago. I thought it was coming because I wiped and there was light bleeding so I put on a pad and nothing. Them 2 days later I wiped and there was light bleeding again so I wore a pad again....then nothing. I haven’t bled since after bleeding light yesterday. I’m cramping and my back hurts like crazy. I took a test the day before yesterday and it was negative 🙄 idk. This happen to anyone??
