I am quite confused about all of this. I tried yahoo answers and they all disagreed with each other, although there was testimony from a girl who went through something similar and turned out pregnant.

I had my last period may 24th.
The last time I had sex was may 30th.

I have begun to have to go to the bathroom more often, I'm always tired, I have bouts of nausea coupled with soft headaches, and my father commented on my strange food selections and asked if I was pregnant.
This is what got me thinking in the first place. This all has other explanations, I know, but there's the framework.

I was slightly anxious yesterday because I informed my significant other about my suspicions, and therefore purchased a home kit.
It came up negative.

So, come today I didn't feel very well. A certain smell set off my stomach to hurting and a headache followed. After awhile it mellowed into a cramp like feeling and was accompanied with spotting, which I am uncertain about. I looked it up online and it said something regarding early miscarriage and all of a sudden I feel very protective of my 'perhaps' child.

So, could somebody tell me does this time frame fit?
5/24 period
5/30 sex
6/24 missed period
7/12 today- spotting

Due to my own circumstances I won't be taking a blood test for another week, so I want to know if there is a chance so that I know if I should be taking special care of myself in the meantime. I haven't done so yet, but the article I saw scared me a little.

Thank you for reading this.
I would appreciate your thoughts.
