I am wondering if it is possible to know you're pregnant within a week or so of having intercourse? It's been over a week now since having sex. My boyfriend did use a condom. However, I cannot depend on my period to know for sure if I am or not. My periods have been messed up for a long time now. Frankly, I have been on birth control but I had to stop getting them because I don't have insurance and they became too expensive. In the past week or so I have not felt myself, I have felt very different. It's very hard to describe. I have had mood swings, cravings, headaches, sensitivity, and fatigue. I know those are general symptoms. But is there a possibility that I could be pregnant? Is it too soon for implantation?
Any help would be appreciated! I apologize for the length of this!
