So my fiancee and i have been trying since Feb of this year and nothing but then he tells me i feel ALOT tighter down there then i do to the point even while hard its hard to go in.. Im usually not this tight at all.. Im 16DPO and 2days late.. The only thing notice is mood swings,some pressure around my belly button, some sharp pains come and go by the belly button, back pain, unusual strong headaches that just come on and make me throw up.. Could i be pregnant?
