<s>[INST] My last period was on 8-20-13. I had sex on 9-1-13. I ovulated on 9-3-13. Im also on birth control pill. I have been extremely nauseated, feeling light headed and dizzy, left pain of and on in my stomach, gassy, peering more, and I was constipated but not anymore. I have also took 2 pregnancy test and they were negative. Am I pregnant? [/INST] Hi, Correlating everything it appears that you may have conceived. It is too early for urine pregnancy tests to come back positive. Please get your serum beta-ChatDoctor levels estimated as this gives you definite evidence for confirmation/exclusion of pregnancy. If the pregnancy test is positive or if you miss your next period, please see a gynecologist before you continue the birth control pills. You may also need a trans-vaginal sonogram. Hope your query has been answered. Take care. </s>
