You can get pregnant the next month after your last period. Your next period will produce an egg about 1/2 way through it. So if your period is 28 days long then the egg is produced about the 14th day. These dates can be different for different people. Even the same person might have some "months" longer than 28 days and some shorter.
If you are having a period, you re not pregnant. You cannot be pregnant until after your last period.
Yes
i had 2 period last month how will i know if i iam pregnent?
No. If you still have you period, you cant be pregnant.
You can get pregnant any time you have sex regardless of when your period was. To find the most likely time when you will get pregnant count back 14 days from the first day of your last period. One month from that day is the most likely time to get pregnant.
No, it just means your period isn't stable just yet. I used to have my period twice a month before I got on birth control to regulate it. It doesn't mean you're pregnant just because you're getting your period every 3 weeks instead of every 4 weeks.
Yes you can.
No test is 100% accurate.
If you're getting your period regularly again, you may be at risk for pregnancy. If you got your period last week, you probably didn't' get pregnant last month.
No you are not
