Than I usually do however I have been off my period for the last 4-5 days and I have been having what feels like menstrual cramps ever since. I feel bloated and just like I'm about to start my period. What can this be?

My last period was jan 10 2011 and I sex jan 15 and sperm actually went inside of me. Lately Ive been feeling nausea,pain on my right side, sleeping , hungry, headache, feeling like I have to throw up but it doesn't comes out, white spot on my nipples while in the shower. My period came on jan 30...

I didn't inside her as I pulled out , can she become pregnant as I think it was very near to her ovulation date ? Help

I just want to know because I get paranoid because I have sex the day after and the day before I start my cycle and never in between and I just want o know if you can get pregnant if you have sex the day before and after you have your cycle?:o
