I have this friend that did it on the first day of her period and she usually lasts 7 to 8 days well this time she lasted 13 days and that's very unsual for her. She says that she has been havig these frequent head aches that make her feel sick and queasy. She's been eating more than she usually do and sleeping more. She didn't use no protection while having sexual intercourse with her mate. She hasn't been vomiting yet and itz been 3 weeks and 2 days since the last time she did it. Also do you necessarily have to have morning sickness when you become pregnant. But the main thing I'm trying to get across is could she be pregnant and does it take some months to get to the point where you start having morning sickness or do some people skip that part of the pregnancy.

Yes, you can get pregnant the first time you have sex, and yes, while it is rare, you can get pregnant on your period.

I have had 4 children and have NEVER had one about of morning sickness. So, not all women get this symptom. I only got breast tenderness with one child. My third child I was 4 months pregnant before I even found out.

If your friend is not ready to be a mother she needs to be using protection.
