Me and My Girlfriend have a doubt that she might be pregnant as her period was due on 18 Feb 2017 and it's already 22 feb. We think it's due to our dry humping on 26 jan 2017. She vomited just 2 weeks after 26 Jan and it is not normal for her as she does not have vomiting problems and she was also feeling thirsty. 3 4 days ago her stomach was aching badly. Her belly is also getting bigger from the front. Now we are so much worried and tensed whether she's pregnant or not. Please Help.
