We are trying for a baby last 1 year. But no result. We did scanning blood test semen count etc .All shows normal result. My last period was on july 5th 2017 and july 11th onwards I had coeadhea plus 75 mg tablet one per day and we are together in July 15 to 28. Normally my period was 30 to 35 days gap. During the medicine time I feel back pain enlargement in breast vomiting headache constipation etc. After completing my tablets on 9th Aug also I feeling back pain and low pain in my abdomen also. I checked pregnancy using one time pregnancy kit on 14 Aug 2017 evening but it shown negative. My periods yet not happened. Is any chance for pregnancy?
