Hi, so I had intercourse on May 16th, and had a normal period a week later. I began gaining weight and bloating, but had a normal period again the next month. I tested on my last day of my normal period, but it was negative. I don't have any other symptoms besides bloating /gaining weight but it's so foreign to me to feel this heavy. Is there a possibility at all that I could be pregnant even if I had a normal period and a negative pregnancy test with only one symptom? I've head some crazy stories.
