Hi. Me and my partner are ttc. We bd'd at ovulation, but I had my period 3 days early (i always have 28 day cycle) and it only lasted for 2 days. The last week I've had headaches, nausea (been sick once!) and a few abdominal and back cramps. My mood is all over the place (the littlest things make me mad and cry!) was just wondering if anyone could help or has had a similar thing?
