Months ago

Months ago I was actively having sex and life was good... and I posted on here and someone told me it was probably that I wasn’t getting enough electrolytes but pregnant women are usually more dehydrated so that’s one thing in wondering... then I gained 20 pounds out of nowhere my diet didn’t really change I was walking and going out to the gym... my face looked more round my jeans no longer fit I ripped some of them when I was out... I did take pregnancy test but they came back negative and I was still having my period well it was more like spotting because it only lasted a day or two... I like 65% sure I was caring a baby
