Can you be pregnant and still have a period with heavy bleeding ?

I just recently had my period. However, it was off and on heavy/light for 18 days!!! I went to the doctor and as far as I know I'm fine. I've had sex since then and just one week after I stopped I've started again. (I started on May 30th, ended around June 16th, and started again on the 21st/22nd) It's heavy as usual when I start and I was cramping and feeling bloated and everything like normal. Could any of this be a sign that I'm pregnant? The whole week I was not bleeding I was getting cluster headaches, feeling very nauseous to the point where I threw up twice, I have been having mood swings, I feel like my body is out of wack, I'm always tired, and I've been having a lot of gas. I don't think it's stress but it could be. I just don't want to even think that I could possibly be pregnant. I'm just not ready.

Don't listen to the idiots above. Yes, you can possibly be pregnant and should get a test asap to make sure. You can also be having a blood clot in your uterus or an ovarian cyst which both can cause spotting, bleeding, and cramping. You can be having a possible miscarriage, however, doubtful from the sounds of it. You can be also having a Dysfunctional Uterine Bleeding which causes you to bleed heavy during periods and spot or bleed in between periods! You need to see a doctor or ER asap no matter what! If you have a DUB, you need to be prescribed hormones, iron, and possibly birth control to regulate your period again since DUB sometimes means you are not ovulating correctly.
