I've been on the pill for awhile, but I skipped it for 7 days or say about 12 weeks ago.
After a few weeks I started throwing up in the mornings and throughout the day sometimes, feeling tired, getting back pains and needing to pee quite often. I didn't have any money to buy a pregnancy test. I kept on the pill and skipped my period pills. About 3 weeks ago my friends notice a change in my body, my stomach was changing shape and instead of being flat and firm stomach it constantly looked like I was bloated. 2 weeks ago I got hit in the stomach fairly hard. The next day I got my period and it hasn't stopped since, and there's blood clots. My stomach no longer looks bloated either but for the last few days I've been feeling sick in the mornings again. Was I ever pregnant? And if so would I have lost it?

Go to the DOCTORS NOW!!
They are the ONLY people that can help you with this situation.

If you were having sex, of course you could be pregnant, if you can't afford a one dollar pregnancy test honestly you have no business having sex since you could not afford a baby.

So yes all of that is possible plus a dozen other things. You need to see a doctor now.
