Me and my husband are trying to concieve baby#1 going on two years now last night was my second ovulation day we had sex I know its to early to tell but today I feel nausea not throwing up and light headed a light tingling feeling in my stomach and lower back pain that is warm so weird cause I've never felt like this before not getting my hopes up but was just wondering if anybody ever felt like that the day after sex and ended up being pregnant.
