My husband and I have been having sex everyday since the 16th and my predicted ovulation day is tomorrow. Do I need to have sex tomorrow or should the sperm from today's intercourse be enough? I have endometriosis and it hurts to have sex if we do it too much...That's why I'm asking for advice if tomorrow is a must. My CM is like egg whites and I felt some pain in my side today so I think I might have ovulated?
