Well, I think I'm confused, too...Unless you were "messing around" with a man and you think that some sperm could have gotten into you, it's impossible. But, see the doctor, because there obviously is something going on if you haven't had a period in 3 months, there might be something wrong.
You need to have sex to get pregnant. Your period can be off for a bunch of reasons, weight up, weight down, stress, sickness. How old are you? When you are really young your period can be irregular as well.
Think you should speak to a doctor.
I would say that age could factor into this ... if you are very young and new into your cycle, it is possible that your cycle hasn't been set in stone yet. Additionally, if you are older and have had a cycle for a while, it is not uncommon for the cycle to change, although this seems to be a long time. Do you run? Do you have an eating disorder? These things influence your cycle as well. If you start exercising intensely (i.e. running, playing sports, etc.) and you haven't in a while, this could definitely postpone your period.
I too would recommend checking with a doctor. However, if you were not messing around with a guy who ejaculated in or close to your vagina or you or the guy touched your vagina with wet sperm on your hand, you are not pregnant. Although rare, it is possible for sperm to travel a small distance (i.e. if both of you are wearing underwear, it is possible for the sperm to travel through the underwear although very uncommon). If you have not been messing around and have not been close to wet sperm, you aren't pregnant. However, I would still recommend seeing a doctor to find out what is going on. Best wishes!
hey ally bear it sound like the same thing i had. i was not having a period for almost 1 year and during that one year i went to the dr almost every other month. i had milk coming out of my breast and morning sickness. the dr told me that i might want to be pregnant so bad that my body was going threw the changes. and one day to a visit to the dr an intern student said that she just study my symptom and that she thing i have a tumor on the pitutary gland so she sent me to get an mri and she was right i had a tumor on the gland. the pitutary gland controls the man and female hormones and the tumor had the pitutary gland to send my body pregnacy hormone. my prolactum level was 156. ---20 and under is mnormal for a non pregnant women so gop and ask the dr to check your blood to see if you prolactum level is high you will be alrught
