Am I pregnant?

So I Am usually regular in my menstrual cycle but in may and June I was late in period, I then had a very light period and don't last long, I started to panic thinking I was pregnant, I had all te symptoms of
Pregnancy but the sickness in the morning ( I had it sometimes through the day) and cravings. I don't use birth control an my boyfriend and I used the pull out method well then I missed my period again for over a month and still had all the symptoms, I took two home tests and they came back negative. So in response I thought it was in my head, a few weeks later way later then I was suppose to I had another bleeding Experiance this time it was light and then heavy but lasted only four days I usually last six. But what ever I ignored it. It's been a a few weeks and I still have symptoms. My boobs are really sore and growing, they have little white dots on the tip that come when you squeeze them. My stomach is sore to the touch, etc. my
Stomach looks bloated all the time which makes me
Look pregnant. Can someone please tell me what's wrong with me?

It's hard to say since some women spot during their first trimester, and some women experience irregular cycles due to stress. Here's info on nipple discharge:

Since it's been a few weeks since your last pregnancy test, take another one. If you are pregnant, the test should have no trouble detecting the pregnancy hormones now. If it's still negative snd you're still concerned, see a doctor. A doctor can help you figure out if something else is going on and administer a blood pregnancy test, which is more accurate.

If you aren't pregnant, while you're there, you might want to check in with your doctor about effective birth control options that might work for you since pulling out isn't a reliable --- or real --- method. You could also learn about tracking your ovulation at tcoyf.org so you can avoid sex during the time of the month when you can become pregnant. You could use at least two methods together like tracking and a spermicide, or condoms and a spermicide. Before I got my IUD, we always used two methods and I never had a pregnancy scare in my whole life.
