We are not trying but would be OK if I was pregnant. I'm late 30s and my periods have been a little irregular since I stopped breastfeeding my youngest a year ago. On average, my periods are 28 days, but some cycles have been 35 days, and the next month my cycle will be shorter by however many days it had been 'late' the previous month (eg, 22 days the next month).
Last month I was 8 days 'late'. I got my period at the weekend. It was a full flow for 3 days. On the third day it had gone away so I had sex with DH and we didn't use anything.
The next day (CD4) I had blood tinged EWCM, a little more EWCM the day after and again today, more EWCM and that familiar pinching feeling that normally comes with ovulation.
My question is if anyone has got pregnant from sex as early as CD3? It seems crazy to me that this would happen and most of my research has led to a firm 'unlikely'. I just want to prepare myself for the remote possibility that I could get pregnant and try to get my head around it now.
