Hello, Im 18 and for about 2 days now I have had pain and tightness all over my stomach, bloating and body aches. I had sex on January 20th and got my period on January 26th and again on February 22nd but it was slightly lighter the second time. I am also on a birth control pill and have been for a little over a year now but im nervous that I was taking irregularly during that time. I just recently got rid of a UTI and have been exercising quite a bit more than usual. Could I be pregnant? Or is this because of the exercising or the UTI? I have also taken two pregnancy tests yesterday and they both came out negative. I just don't know what else to do. Any answers? Thanks.
