When did you find out you were pregnant with twins?! I have a feeling that I could be. I found out I was pregnant two weeks after I had sex. I'm now entering my fifth week of pregnancy on Monday. I'm already extremely moody, my boobs are extremely tender, my nipples hurt and are more veiny and are looking differently as well, I'm beyond exhausted, I get nausea but I haven't thrown up. I know how far along I am from blood testing (only received one test). Levels were at 42 on the 13th of this month. Any insight would help, thank you ladies.
