Two weeks ago on Sunday my bf fingered me before I gave him a handjob. After that neither of us touched my vagina (but I might forget if we did, but even if any of us did touch it, it was thru my jeans). Two weeks later my period came, 4 days earlier (my usual cycle is 31 days), lighter than usual but the colour’s still bright red, had less clots than usual, & the cramps are a lot milder. I usually have really bad cramps. today is day 5 and the bleeding has stopped (i usually have 6-7 days of bleeding though), only brown, old blood discharge, but my boobs are still painful. Other pms symptoms are gone though & i usually stop experiencing pms pains on day 2-3. Question is, could my bleeding be implantation bleeding? Because my breasts hurt on and off, even though I’m supposed to stop experiencing any pain 2 days ago. Thanks.
