I made love with my Fiance April 16th. I believe I was ovulating April 15th through April 20th. I didn't get my period. I am peeing a lot. I sometimes get lightheaded. I have been feeling really tired more than normal. I am more emotional and sad. My back hurts. I feel like my stomach is full and between my stomach and my lower area it is swollen it looks like. I am asking this question because I am afraid my test will be negative. It's just me being insecure. Please help me. Thank You!
