Hi, I need help understanding my situation and cycle. It is stressing me greatly. My last period was may 6th then I discovered I was pregnant and went for an abortion june 25th, bleed till 6th july. Had sex using only withdrawal method on the 9th of july. Bleed again 10th & 11th though lighter in colour. Had sex on the 23rd of july twice with only withdrawal method only again. According to my period calendar I am 4 days late. Did pregnancy test on the 25th and 30th of july cos I felt disturbed and both were negative. I have been having headache for days now, urinating more frequently, love peanuts more now, had abrupt nasal congestion but clear now. On the 2nd of august I started experiencing lower back pain till now and had slight abdominal cramps as well. Cycle not 28 days. Average around 33 days. I need help understanding all please.
