Ladies,
Me and my partner have been trying to conceive for the last 7 months. The last 2 months my periods have been very short last month being 2 days and this month last 1 day. I took a test after last months period and this was negative. I'm yet to take one this month. Does anyone have any thoughts? Could this be good news?  Xxx
