My period was supposed to start the 11th but it started the 10th I bled like medium that day and on the 11th is was light and 12th and 13th it was only spotting when I peed. My periods are normally real heavy and last 4-5 days then spotting for 2 days but during my ovulation week last month had sex first two days of it and have had swelling and pain in lower abdomen and my pelvic and it didn’t go away until few days before my period started this month but I still slightly have a little bloating look and normally I don’t. I took a pregnancy test other day and it came back negative is it to soon to test or what could it be? Help please!?
