If your periods are usually irregular, you should see a doctor for tests.
Probably around six weeks.
About 32 weeks because about four weeks per month
Fourteen days after intercourse or the day of your expected period.
Assuming you mean "first Month" the answer is yes. With a very sensitive pregnancy test some pregnancies can be detected as early as 3 weeks and 2 days; this is the first month of pregnancy. Most pregnancies are easily detected at 4 weeks on the day of your missed period with a early pregnancy test this would technically be the beginning of your second month.
It's not advisable no. Taking the pill for one month will not prevent pregnancy as you need to be on the pill for 4 weeks before you can have unprotected sex without the risk of pregnancy.
There are pills to abort pregnancy after you have missed the period for 2 to 3 weeks. Any way consult your Gaenacologist for expert advice.
it will be almost nine months of pregnancy
unless the next month you miss your period and you dont have one no. Cramping and nausea come with your period
yes
yes you can. i had period pains about 12 weeks into my pregnancy. i am now 37 weeks pregnant.
you count how far along you are by the first day of your last period. So by the time you miss your period you are technically considered 2 weeks pregnant.
Usually the first visit is after you have missed your second period, roughly 8 weeks.
