I had unprotected sex on july 25,26,27 and my last period was on the 14th July. A week after having sex i started having strong sence of smell, i was experiencing faigue like never before, i was feeling bloated and was having sensations in my lower abdominal area. 5 days before my period i started spotting on and off for 2 days then again a day before my period i was spotting. Then when my period started it was bright red and this was unusual for me it lasted 3 days as usual and the last day the blood was brown. after that i stopped ''feeling'' pregnant. then all of a sudden a 5 days after my periods i start having pains where my ovaries especially when i walk and then havig cramps later on. What could all these mean? anyone can help me here? i took a test before my period and it was positive and then one after which was negative
