Welcome back to icliniq.com.
I read your query and can understand your concern.
There is no chance of pregnancy since there is no penetrative sex. If there is penetrative sex, then you need to be bothered.
You missed your period for almost two months, and if you had unprotected sexual intercourse, it would be detected at any cause. However, you can give a blood sample and test beta hCG levels if you doubt.
I hope this helps.
Thank you and take care.
