I had sex with my boyfriend on August 6th, we did not use a condom nor am I on birth control. He did the pull out method but my legs were spread at the time and I felt some get in. Days later I was nauseous so I thought I would take a test. The first test I took (First Response) came up as “error” so thinking I peed too much on it I peed in a cup and put the tip in for 5 seconds as directed. It came up again as “Error”. I tried another brand “Equate”, both test from that brand came up “Error” as well. We had sex again on August 11th, did not use a condom that night either. When he pulled out he finished on my lower stomach to my vagina. For the past few days I have been feeling sick through out the day. I also have low energy while working which does not usually happen because I take medication for my ADD. When we had sex on August 11th it was the day of my ovulation which put me at high risk (33%) for pregnancy. I am supposed to get my period on August 26th. I do not want to buy another test and have it show as “error” for the 5th time. I would like some answered as what to do, Please help! Any suggestions would be appreciated!!
