Okay so my boyfriend and I are very active.. We have been together for almost 5 years and I was on the pill for quite sometime but about 3 months ago I stopped after some weight gain (120 to 165). We have been using condoms but last month the condom broke. The next morning I went to a local pharmacy and got plan b (I didnt want to have to but only being 19 I did). But the past 2 weeks I wake up feeling very sick or go to bed feeling very sick. And I am constantly exhausted, but I also re started my birth control about 2 weeks ago. Could it be side effects from the pill or should I take another test or go to the doctors for a blood test? I took a test about a week ago and it was negative.. Could it have been too early??
