HELP! Light spotting, headaches, bloating, tired. Am I pregnant?!

[xelapop]

So, I've been feeling really bloated these last few days, I've head a headache that won't go away (even though I get these from time to time) and I thought I could be pregnant. Took a pregnancy test and it came back negative. However, now I think I'm on m period, but it's extremely light and I would even say it's just spotting. So, I don't know what's going on!! I have irregular periods anyway but this is just weird. Can anyone give me some advice or input?!

It's fairly common to have spotting in early pregnancy.  Have you tested again?  Do you know when you ovulated?
