No he isn't wrong. The day you have sex and this is the day you became pregnant (day 1) your already considered 2 weeks pregnant.
No, you can't get your period if you are a week pregnant. It is not possible to menstruate while you're pregnant, but you can bleed for several reasons - if you do experience bleeding during pregnancy it could be miscarriage so talk to your doctor.
If you just had your period two weeks ago and you are on it again, this could mean you are pregnant. It may also mean that you have an illness. You should see a doctor soon.
Normally, you should not have your period if you are 8 weeks pregnant from my understanding, if this is happening go talk to your doctor. but please be sure to correct me if I'm wrong.
Your pregnant !
If you have had your period for three weeks, I would suggest you see a doctor. I am a male and do not know all there is to now about a women's cycle, however, three weeks does not appear to be normal. See your physician.
If you had a normal period, even 2 weeks late - most likely you are not pregnant.
It is possible. I suggest getting a blood test done at the doctor's.
It's highly unlikely but not impossible. See a doctor ASAP.
Could mean you are pregnant. Or it could mean your cycle is changing.If uncomfortable see your doctor.
Yes, there is a high chance that she could be pregnant
Could be implantation bleeding. If it is your actual period then it's unlikely that you are pregnant.
