I don't know if I'm just worrying to much or if in pregnant.

1) my period usually is irregular but for the past 6months it's been the 7th but it's late.

2) on the day I was suppose to get my period, I had light pink all over my pad not alot but maybe 3 inches long but very faint

3) my boob's have been sore and look a little more round for a week

4) I had heartburn after eating hotfries chips

5)every morning for 4 days now I have lower back pain waking up.

6) I have little white pieces coming out my vagina and it's kinda wet sometimes

7) if I don't eat for a couple hours I start to get like a head ache and feel like fainting but only for a lil. I know long sorry can you ladies help what do you think
