Pregnancy Info HOME

Hello, I was on birth control for 3 years and went off of them last month. I had unprotected sex a week after the start of my period and about a week after that I had been having weird symptoms like nausea and fatigue. The symptoms then started getting worse, along with bloating, heavy discharge and moodiness. I was late on my period and then it came 4 days late. It was very heavy, lasted a little over three days and I was waking up in the middle of the night with horrible cramping. I was sure I wasn't pregnant after that. so just to be sure a week later I took a home pregnancy test which came out negative. I still am very tired, have been getting headaches and feel slightly nauseous. I have also gone back on my birth control starting the Sunday after my period. I am not sure if all these symptoms are because I am messing with my hormones, going on and off the birth control or if I can actually be pregnant with a period and negative hpt. I just don't feel like myself lately. I am not ttc. Anyt help would be great because I have been worrying about it the past three weeks since the 4th of June. Quite possibly I am imagining symptoms because of the stress and worry of being pregnant. :(
