Okay I am currently taking all these medications Metformin to regulate my menstrual cycle, synthroid for my thyroid and prednisone. I have been taking metformin know for 3 years my cycle has been regular. Synthorid and prednisone i have been taking for like 3 months i have not started my period i am late 4 months. Me and my partner have been having unprotected sex for about 5 months this entire month i have been cramping, once in a while i will get a sharp pain by my ovaries and well this past week my nipples have started hurting. Is there a possiblity that i can be pregnant?
