Last month i got my period on march 22nd , I usually have a 30-32 day cycle, on the 11th of this month my bf and I got a little carried away and we dry humped, he had no clothes on and i was in my underwear still, there was no ejaculation but there might have been some precum, yesterday the 22 i tried a home pregnancy test ( two because i heard you can get faulty results on some) it wasn't the first urination of the day but it was in the morning and they both came out negative, but my back and breast have been hurting for the last week and half and ive had discomfort where you usually feel cramps on your period. could i be pregnant? and if not why am I PMS-ing so bad because i never usually do
