Okay here goes. I'm really worried about being pregnant but it's to early to take a test.

Facts about me:
1- My boyfriend and I just starting having sex where he "finishes" inside me
2- I'm on the pill. I did mess with it a little as far as taking a different kind for a week.
3- I have been on the pill for about 5 years
4- We have sex (as stated above) about 4 times during my ovulation week.
5- I am still 7 days away from my next period (but it always comes 5 days after this) so I should get my period in 12 days

Things that are scaring me:
1- I have been having really weird pain in my lower abdomen for a few days
2- I have had CRAZY cravings for meatloaf (I hate meat loaf)
3- My breasts are so tender and my nipples are very sensitive and erect most of the time
4- I've been exhausted. Over the last 2 weeks I can't even tell you how many days I have gotten home from work and just went right to bed

It's to early to take a test and I was just wondering if I'm crazy or if anyone thinks there is a chance I'm pregnant. I'm looking for other options as this is really not the ideal time to be pregnant. Any advice is appreciated.

Of course there's a "chance" you're pregnant. Nothing is 100% effective, particularly if you take the birth control as prescribed.
