I am married women and having an affair. Last week I visited the doctor and he told me that I am four weeks pregnant and I am worried because I am not sure who impregnated me since me and my lover didn't use protective and we had sex the last time on the 10th February. My lover seems to be sure that he is the one who impregnated me. My main concern is that Is there any health risks /complication that I may cause health wise to my husband if he is not the one who impregnated me? The other thing is that I don't want to jeoperdise my marriage
