If you are young or you are very active, you may have very irregular periods. But it would be best to discuss this with a Doctor Who knows your health history.
na. you do something around about every 3 months. That way she knows you are still interested in her
Yes sometimes as someone I know got a signed photo it sometimes takes up to 4 months or even longer for them to reply though (:
50 months is longer 4 years x 12 = 48 months
A passport takes about 4 months to be approved however if there are complications then it might take longer. If you have a background then sometimes it takes much shorter then 4 months.
If you just recently started getting your period, within the last 6-12 months (sometimes slightly longer), then something like this is completely normal. While your body is adjusting to the higher levels of hormones in your blood, you can have irregular periods (meaning they can skip months, be extra long, short, heavy, or light) Of course there is the possibility of pregnancy. If you have never had sex, then you are not pregnant. There are other rare medical conditions that could be the cause, however these are rare (considering your age). If you are really concerned talk to your mom or your doctor, but it is likely that your body is just growing into itself and getting used to the changes that are happening.
Until the pregnancy hormones have settled which can take up to 2 months and sometimes longer of you had a late abortion.
Yes, pretty much. Sometimes it can take longer for the breast milk to dry up.
A year is 12 months, so 3 years would be 36 months...longer than your 30 months.
10 weeks is longer and 2 months is shorter
9 months after you become pregnant sometimes more sometimes less but the average 9 months
Months are longer on Earth than they are on Jupiter, because Jupiter's days are only 10 hours long.
They are the same.
