History:
About 5 or 6 months ago I went on the pill and started to have sex with my partner. We used condoms every time in addition to the pill to be extra careful, but we ran out and had sex twice without a condom *while on the pill*. I had been on the pill for about 2 or 3 weeks when we had sex without a condom. Our relationship ended pretty quickly and I haven't had sex since the end of September.

Reasons I think I might be pregnant:
Lately my friends have been saying, "That shirt looks good on you. It makes your boobs look really big!" My breasts have felt sore. While I was on the pill, my periods were lasting about twice as long as usual, and I was spotting a lot. Maybe the pill was the wrong strength? I went off the pill about 2 months ago and haven't had my period since. I stay really fit and I have good abs, so I wonder if this is why the pregnancy might have taken so long to show... if my muscles have been sort of holding it in. I have been bloated, despite the fact that I have gone from vegetarian to vegan since January. Also, I have been having unusual cravings, been sleeping all the time, crying, and getting headaches way more than usual.

Any input and opinion appreciated. I will pick up a pregnancy test as soon as possible... I just want to hear what people think.

Thank you!
