I have a question. Me and my husband have been TTC since August with no luck. Clomid did absolutely nothing so this cycle I'm taking femara. My cycle is normally anywhere from 28-32 days. And today is my cycle day 19. Last night I had cramping out of no where.. It was extreme pain like when I have my period but it felt like the start of my period, but my period is at least 10 days away. It started at around 830pm and lasted until almost 2am when I went to sleep. What could this mean, if anything at all?
