Yesterday me and my boyfriend had sex. Im on my 10th day of taking contraceptive pill. But today I accidentally forget to bring my pill and im on a out of town trip and will be home by tom night. Based on my calendar.. today is my ovulation.. and as i do my research they say that sperms can survive inside until 72hrs. As i'll not be having a pill tonight is there a chance of me being pregnant? Pls help me to answer my question as im a lil worried. Thankyou for ur time.
