I had a period on the 10th-13th of this month. Had unprotected sex on the 22nd of this month and he came inside of me twice. Started light spotting on the 24th that lasted a day. Not 100% on my exact cycle days, but I have one every month. I would say every 28 days? So I'll go off of a 28 day cycle, I should start around Feb 6th...? I have been nauseous (nauseous while pregnant with toddle but never threw up) and have some headaches, notice myself snapping at the little things, and feel a little more tired.. I told the guy what was going on and he said he is pretty sure he "shoots blanks" and has never had a scare.. Could I be pregnant? I have a toddler but didn't know until I was 16 weeks. My nipples burned BAD in the beginning (when I didn't know I was pregnant) and experienced that same tingle burn one time thus far but very mild. Am I wigging myself out here? What should I do or think at this point...?
