First let me say, this may involve a little tmi. I had a miscarriage back in Marxh of 2010. Cycle became irregular for about a year after. Starting August 2011 it seemed as if we were back on track. Af started coming every month, even tho my calendar said otherwise. Skipped Febuary and July 2012 but had one every month since. My last one was November 22, 2012, keeping in mind I have an average of 49 day cycle, no af for the month of December. Had unprotected sex with husband December 17th. Fertile from December 22th to December 27th. Ovulation date was December 27th. Had unprotected sex that day also. Started spotting on January 3rd just when I wiped and only once that day. Started feeling really bad for the next couple of days. Nausea, fatigue, and thirty. Spotted on the day of expected period, December 10th, same as before. Now have really bad headache, some nausea, urge to pee, dizziness, back pain, missed period, feeling of a nosebleed with no blood and burning/stinging felling in nose, neck stiffness, feeling of being sick (flu or cold like), and pain on left side. Negative test on the 10th, could I be pregnant or could it be something else or could I just be dreaming it all? I really want a baby. I'm 25 married and am raising my husband's two kids. I would really LOVE one of my own. Any advice, comments (non negative), experiences, and luck will go a long way. THANKS in advance all!!!!!!
