Post IUI symptoms

Sarah • TTC #1 for 2 yrs, did 4 rounds of femara, 1st IUI on 11/15 & it worked!!! ? Due 8/8/15 with twins!! ?Praise God! ?
Hey everyone! I had my first <a href="">IUI</a> on Saturday & am getting discouraged because I'm cramping like I normally would during the last two weeks of my cycle! I cramp a lot so I'm not sure if this means it didn't work or if I'm just a crampy person bc of my endo! Anyone have similar symptoms?! I have been praying sooo hard that it worked!! ???
