Not really sure whether I need to or not. My cycles are long due to PCOS anything from 30 to 40 days long. My last cycle was 40 days so i'm on day 21 now, we didn't use a condom last night and as sperm can survive for up to a week that could take me into the time when I ovulate I think but i'm not sure due to the erratic nature of my cycles!
So words of wisdom what should I do?
