pregnant???

Sarah

so about 3 weeks ago I've decided to start losing weight so eating healthier and working out more. Me and my boyfriend have sex alot and we mostly use condoms but there has been times where we haven't and he just pulled out there was this one time where I was 5 days late on my period and he pulled out and it got all over my inner thigh but didn't know if a little got in. I am now 25 days late I have taken two pregnancy tests and both have turned out negative I probably took it about two weeks ago then one last week. Was it to early to even take those tests tho? I haven't had any symptoms of pregnancy yet but I have been having super bad acne like I'm about to start for the past week. Is there a chance my period is just late from the exercise and new diet or is it cause I'm pregnant?
