So, my last menstrual cycle was 4/3. I ovulated 4/18-24. I had intercourse multiple times in that time frame. On 5/5 I test negative for pregnancy. But I have been nauseous, hot flashes, my appetite has changed...I now drink pickle juice (it helps my nausea...which is kind of off & on ...more on than off), headaches, I'm bloated, super gassy, having mild cramping feeling, creamy cm, dizziness, & lower back pain. Also, my AF is past due.
