I have been having unprotected sex with my boyfriend for a month, he ejaculates outside but I havent gotten my period. I used to be a heavy marijuana user and stopped completely on jan. 5th without using any method, I smoked more or less a gram a day for the past two years. The only pregnancy symptom I have are sore nipples. I have also been going through all the withdrawal symptoms from marijuana and have been under a lot of stress. Could I still be pregnant? The tests I took were all EPT. I guess what I am asking is if I should see a doctor or is my late period is also an effect from ceasing to smoke marijuana cold turkey?
