My period has been late for the past two months.. I was suppose to receive my period 2 days ago . I have to urine a lot more frequently especially within the past week. The other day I expierienced a sharp pain on my right side near my ovaries with a little bit of tingling. I also find myself having more of an appetite, as well as some nausea. My bowel movements are okay but I most likely don't use the bathroom as much as I should be. When I lay on my side sometimes even when im laid on my back too It feels like theres so much pressure at times. Can you tell me what it could possible be? I took a pregnancy test last month when I was late but I was good came out negative. I did not take one this time because I feel it has to be something wrong with me. Hope you could help me out.
