I have been experiencing very sore nipples for the past week or so. My period is not due for another 2 weeks and I am always very regular. I have in the past experienced slightly sore nipples maybe a day or so just before my period. I had unprotected sex on April 5th and according to a fertility calendar, I would have began my fertile time on or around April 4th. I have not experienced any other pregnancy symptoms, however, I was a little nauseaus about 3-4 days ago but I wasn't feeling well at that time either. I know that it is too early for a HPT, but do you think I could be pregnant?:confused:
