I am 22 and my bf is 25 I dout I am pregnant I have taken home pregnanct test and it came negative I have taken a lab test but that also came negative but I dont know why I am not getting my periods.According to me if I am pregnant then atleast I should get some sign I mean forget about the symptoms but a lab test cant be wrong isin't it???. I am posting my case also I have got no symptoms of pregnancy.I dont feel any heaviness of breast,no blue veins on breast,no sickness nothing just white milky discharge is flowing.

I am 22 and my bf is 25.Me and my boyfriend tried to have sex on july 10 he didnt wore a condom first when he tried to enter me.He just kept the tip of his penis on the opening of my vagina and pushed a little(only half of tip went in) but I felt too much pain so he removed his penis immediately(no semen came out from his penis only pre ejaculatory fluid) after some time we again tried and this time he wore a condom and fully entered me but as I was feeling too much pain he removed his penis and that was the end for the day. In the month of july(on 28) I got my period for full 5 days but in month of august when my period date was nearing i.E on 28 I developed internal heat due to immense drinking of tea and coffee (as I work in call centre and have to work in irregular shifts) and I used to feel pain in stomach and a drop of blood use to come in a day this went on for a week(i have irregular periods).Now the date has passed for august still now I have not got my period my question is that am I pregnant?And one more question is it necessary that sperms should go deep inside the vagina to get pregnant I mean if he rub his penis on my vagina and no sperms have come out and just the pre-ejaculatory fliud then also can I become pregnant I have heard that there are only 5% chances of getting pregnant due to pre-ejaculatory fluid.
