Am 24, I had a kidney transplant over 2yrs ago, I been having unprotect sex with my husband but I have never get pregnant at one point we believed i did but it was a mental pregnancy, I was hurt when I found that out because we were 100% sure that I was pregnant, my period is late for 2 wks now, I have no pegnancy symptoms but I see that my belly feel hard and look bigger even some of my pants don't fit me, I weight my self and still on my normal weight, am worried that if am not pregnant it can be something bad, I want to wait two more wks to take a home pregnancy test, I know that if am pregnant there will be a lot of things that we will have to look into because of the risk that the baby will face because of all the medications that I take and if am not pregnant what could it be, please give me some advises, am scared and confuse, should I just seek medical attn soon?
