I have been on birth control for a while and have made sure to take it at the same time every night 10pm. I had unprotected sex with my boyfriend in about the third week of January. And he pulled out. I have gotten my normal withdrawal bleed for January February march and April. I am worried about a pregnancy. I have been working to loose a little weight and have lost about 9 pounds so far. My waist measurement has decreased an inch. I haven't taken a test bc I am worried what it will say. I haven't really had any common pregnancy symptoms, except bloating with sometimes comes at night which I have experienced before this worry. I feel as though it may be regular stress that is making me worry. Does this ensure that I am not?
