Thanx for your reply to my query that I posted yesterday, as what you told me that since my girl had her periods start off on 20th last then it's still not late, again what she describes is the process of ovulation where the liquid in her vagina has dried up, now what I want to know is the fact that the liquid has dried up and she feels dry inside does that mean that she is bound to get her p's started in some time ( in other words nothing to worry ), again does this thing dry up if the girl is not gonnna get the p's also, In other words I am a little worried as she has not got her's p's yet but do u think that if there was something wrong then she would not have experienced the dryness which she normally does before her's p's start, again as I said last she got them on 20th so what according to you will be "LATE" for her....plz throw clarity here
Without knowing the history of your girlfriend's periods and how old she is - I cannot say. Teenagers are not usually regular. They skip months, have 2 periods in a month - this is normal. If they are under stress they may be early or late - this is normal. A teenage girls periods are not usually always on time until she is about 16 -18.
Now what is regular for one person is not regular for another person. Periods do not come on the 20th of every month. They come every 28 days or every 30 days or every 21 days or every 36 days - all normal. Most common is for a girl to have her period every 28 days.
If a girl has her period every 30 days - it might seem like she has it on the 20th of every month because most months have 30 days- but some have 31 and some have 28 - so she would not have her period on the 20th when this happens.
Sex is risky business. There is really no way to be absolutely sure you are not getting a girl pregnant when you have vaginal sex with her. That is why every time you have sex you should think is this a person I want to have a baby with - or trust her to know she will ( or will not) have an abortion or give the baby up for adoption?
If you can't handle that responsibility you are not ready to have sex. It sounds to me you have a lots of fear around pregnancy and don't particularly trust your girlfriend to understand her own body. You need to learn to trust her ---- and of you can't you need to stop having sex.
