Hi I am 45 and my last proper period was 20/10/12. I had 1 day bleed in November and December and nothing this month. Now I have very tender breasts, lower stomach cramps , bloating , nausea, headaches etc. I have done 3 pregnancy tests all were neg results. Could I till be pregnant? I am worried due to strong pain relief meds that I m on etc. Please help, thank you
