I’m experiencing extreme hunger but when I eat I get so nauseous and tired and I’ve had horrible headaches. I’ve been like this for a few weeks now. My birth control was removed in 4 months ago. The last time I had sex was 5 months ago I had the Implanon but was on heavy antibiotics the last 3 months I had sex. Could I be 5 months pregnant? The test say no but with my first I had to have blood tests to know also I’m RH neg or is it just coming off the birth control I’ve had no spotting .
