Pregnency

I am 22 and my boyfriend had an intercourse with me but he withdrawed his pennis before ejaculation and even he inserted them half a way I am still a virgin and I do not got my periods from last two monts I also expected my weight loss and pain in my uterus followed by decrease in my breast size tell me what to do I am really worried ?

#1 "pregnency" is spelled "pregnancy"
#2 You are NOT a virgin
#3 You are probably pregnant
#4 See a doctor

First of all, any penile-insertion into the vagina makes you not a virgin.

Withdrawal is not a reliable method for pregnancy prevention. Guys have pre-c*m which can contain sperm which can make you pregnant.

Seeing as how you have missed your last two periods I would say you should be worried that you are pregnant.

You should see a doctor ASAP and start prenatal care.
