Hi i am 20 years old and my partner and i have been trying to have a baby. 2 weeks after our first insemunation i was supposed to have my period but it was ten days late. I got the normal cramping but this time it was way worse than usual. Not to mention i was vomiting.  Keep in mind this was just last month. Well this month I was supposed to start my period on the 25th but am now 4 days late? Is my cycle just out of wack or could i be pregnant.
