My last period was feb. 21-26 I had in protected sex the 26th & 28th and March 14th. My period isn't due till this Sunday BUT! The last two days I've felt bloated.. I'm restless at night and occasionally feeling nauseous. Today I had some very very light spotting, 3-4 drops and that was it.. Now nothing. I have some mild "cramps" but they don't even feel like a cramp.. It's just enough to know something is up.. What do you think? *side note none of this started till the 16th.. If I am pregnant would it be from the sex on the 14th? All with the same guy might I add.
