I came off my period on the 27th may and had unprotected sex on the 2nd and 3rd of may could i be pregnant? I dont really no when my ovulation days are as I can never remember when im due on my period i tried a few ovulation calculators and they either say i was or a couple of day - week before. is it possible that i could be pregnant? since then my breasts have been tender but had no bleeding or cramps...
