Me & my husband have been trying to get pregnant for over a year now. Well just a few days ago was my ovulation day. I have been paying attention to my body and I noticed that I have had cramping on one sided and then they would jump to the other side. I have had terrible bloating and I am always tired which is usually not like me. I have also noticed that I have alphas pain in my back. Are any of these known for early pregnancy signs?
