So I got my last period March 1st.

I had unprotected sex late the 14th/early morning the 15th.
no condom, birth control, or anything.

I was worried about that so I looked up my ovulation date for this month on some website, it said that with the date of my last period & normal 28 day cycle that i ovulated on the 15th.

it's been about 16 days since then , i was suppoused to start my period 3 days ago on the 29th but it still hasn't came.

as far as symptoms
I've been really tired, like to the point were i just lay down all day, even when i am awake my body is like physically exhausted, I've been taking alot of naps during the day.

& headaches, the first week after the 15th and a few days after i was having horrible headaches which is really weird for me because i never get headaches.

the past few days i started cramping very lightly though, before i start my period i usually cramp pretty bad, but these cramps are different, they're not nearly as bad and they come and go, like I'll hardly feel them most the time.

my breast are sore to the touch, its not like unbearable though.

I've had REALLY bad heartburn the past 2 weeks,

and I've had a sour stomach, i had to run to the bathroom several times thinking i was gonna get sick, i haven't accually thrown up but I've been really queasy.

If i don't start my period by next Monday im gonna take a test. since that would be like exactly a week after i was suppoused to start.
