Hello, On the 4th of Feb 2017, my girlfriend and me performed sexual intercourse. Apparently, we had not used protection. But I had not ejaculated in her. Three weeks later, just a day before her periods began we did it again without protection and I didnt ejaculate again. Lately, she has been showing signs and symptoms of pregnancy like giddiness, nausea, morning sickness, cravings, etc. Although she had her period at the end of last month, she is going through this. Is she pregnant? We haven't taken any tests yet. When would be the preferred time to take it? Is there any natural way to prevent the pregancy from happening now, if at all she is pregnant? Waiting for your reply
