Hi, about 2/3 weeks ago I had an "accident" with my boyfriend during an intercourse. Now my period is few days late, which is weird as it is always very precise coming every 28-30 days. I didn't have any PMS symptoms but my boobs are sore, sensitive and tender and according to my boyfriend much bigger as well.

Last night I put a tampax on hoping for "good news" and this morning I noticed a light spotting on the tip of it .. Still no period tho! Could it be implantation bleeding? Is this ever happened to you? Should I start getting worried? Also is it too early for a pregnancy test? Thanks :)
