Hi I had my period on the 10th November and had unprotected sex on the 17th. On the 2-5th December I had really sore boobs (never experienced this before. They felt really full). And now today 7th December I have some spotting but I'm not due for my next period until the 14th December.. I've done a home pregnancy test but it came up negative so not sure if It was too early or what. Could I be pregnant?

At a few weeks, no your boobs are not "full" . In fact normally there are no signs until a missed period. But of course you could be pregnant, why did you think you may not be ?

You tested way to early. You can not test, till you are 2 weeks late for period. So sit back and wait another 3 weeks and see if you get period
