Hi welcome to health care magic...
You had history of unprotected sexual intercourse in past(12 june) ...
As you have not used any barrier method , chances of
pregnancy is there ...
To rule out it you can investigate with.....
1.Blood
HCG estimation (comes positive 3 week after last LMP,if conception there)
2.Urine HCG estimation (comes positive 5 week after last LMP,if conception there)
3.Transvaginal USG for further confirmation
I hope these investigation will help you for rule out pregnancy...
You can choose blood hcg estimation if want result earlier..
The symptoms of pregnancy is delayed
menstruation, sore nipple, pigmentation of
areola ,spot bleed from vagina etc...
Advise :gynecologist consultation if needed ...
Take care
