Could i be pregnant?

I haven't really had a period since april because my birth control was all messed up. I just stopped birth control about 2 weeks ago after the last time I had sex. It has been about 4 weeks later and I'm moody and want to cry and today I woke up and...

noticed that my nipples are sore and chapped and the past week I have been having mild-severe cramps. Some more sharper on my left side than my right. The only thing I can think of is pregnancy or a cyst? But would a cyst cause chapped and sore nipples(by the way this is the first time I have experienced this)

It's very hard to answer your question since there are too many variables. What do you mean your birth control was messed up? If you missed a pill then there are chances of you being pregnant. Have you checked for pregnancy? There is a very slim chance you got pregnant despite being on the pill. Most important of all have you seen a doctor? It is not normal to have chapped nipples nor sever cramps. Why would you think it's a cyst? This is all things you should discuss with your doc as soon as possible.

You should see a doctor. However, it's pretty unlikely that you're pregnant because without a period you're not ovulating.
