Hello
Thank You for contacting HCM.
I read details carefully.
These can be symptoms of PMS (pre menstural syndrome) more likely.
To be pregnant, 2 criteria should be fulfilled: 
1. Fusion of sperm with ovum to form a fertilized ovum. 
2. 
Implantation of the fertilized ovum in the 
Uterus. 
As per details  there was no ejaculation so there are no chances of 
pregnancy. 
There is no need to worry, you can wait till you get your periods. 
If they are delayed more than three weeks, a Pregnancy test can be done to confirm it. 
In case of pregnancy, it will give a positive result within one week.
I will suggest you to avoid 
unprotected intercourse if you do not want pregnancy.
In case of overdue of your cycle, go for pregnancy test and Pelvic scan.
Consult with your Gynaecologist.
Hope this answers your question. If you have additional questions or follow 
up questions then please do not hesitate in writing to us. 
Wishing you good health.
