My period is usually on time and heavy, this month I was 4 days late and on fourth day I started bleeding lightly now for 3 days I've been bleeding but it's lighter than my normal period. What is wrong?

Three options.

1. Like you said it's possible you could be pregnant.
2. You could simply be late- this happens from time to time and is worse with stress.
3. There's something medically wrong- not likely but it's possible.

If you're really worried take an in home pregnancy test or see your doctor.

I wasn't stressed or anything before I was suppose to start my period. But I'm not sure if I'm having implantation bleeding or not or if it's to early to take a test.

It would be too early to take a test. You shouldn't test until your period is at least 2 weeks late, then test using first morning urine.

Wait and see what happens with this bleeding. If you feel it's not a normal period, test when this period would have been 2 weeks late. If that test is negative, wait and see what happens with your next period.

It's possible you're just having an off month. It happens to all of us at least once in our lives.

Good luck.

What worries me is me and my boyfriend had unprotected sex exactly 6-12 days before this bleeding started. I've never had such a light period before. Anyway thanks I guess I'll just wait it out and see what happens.

Well the spotting got lighter and stopped, so now I don't know today would make me a week late for my period. I'm very tired and bloated all the time it feels like. I'm not sure what's going on.

Wait another week and test using first morning urine. There's no way that you'll know what's going on before then.

Ok thanks
