Talk to General Physician on Dental + Gyne

Dear doc, I had complaint of gum swelling for which I consulted a dentist. The dentist gave me medicine for 4 days. 1+1.. I took it for 1 day and started have pain in my stomach with several motions (not loose motions). After that I completely left the medicines. Now after 2 days ( I m not taking the medicine now) I m feeling nausea, fatigue, I m vomiting whatever i m eating. I am trying to conceive also. I don't know am i vomiting because of medicine or I've conceived. Although I have 18 days left for my next periods. I am attaching the prescribed medicines. Thank you
