I had a pulling sensation in my lower abdomen a few days after ovulation. Sore boobs, achy feeling in lower abdomen as well as tender to touch. Nausea off and on, headaches more than normal, and not feeling like myself. I missed my period by 5 days, took a 2 home tests, one negative and the other came up with a faint positive line, and had one day of heavy period and 2 days of spotting. My periods usually last 6-7 days. I still have all the same symptoms as mentioned above. Is it possible that I am pregnant?
