I have been monogamous with my husband of 3.5 years. I had been with two men in the previous 5 years. I knew the status of one of them, we had a long term relationship for 4 of those years. The other was a one night situation...I had been physically abused as well as mentally by the long term relationship guy. I guess out of sadness and wanting to be accepted, I let my guard down. I do not know this man's std status and we didn't use protection. I am having no symptoms of anything yet now that I am pregnant, I am worried sick if I have AIDS or something. I know I will be getting tested for everything but it makes me sick to think about waiting for results and what do I do if I am positive for something? My husband has been tested twice in the last year for life insurance policies. I am afraid of even getting life insurance for fear of being tested and waiting for results. What are the chances of contracting HIV from someone you don't know their status and what is the chance after a one time encounter if they were positive? Is it a given that you have it if you had sex one time? I am so sad.
