On June 22nd I took a test and it came back positive but it was rather faint. From then on I was dizzy, nauseous, was cramping which wasn't associated with my period and dizzy. Unsure if I was actually pregnant I took another test on July1st, this time I was sure that I was because the test was again positive. On July 4th or 5th I started to bleed. It wasn't as heavy as my normal flow, and only lasted 4-5 days. Which is odd considering that my period is like clockwork starting the 20th or 21st of every month and lasts 4-5 days. About a week or so later I went to a health clinic and took a test and it was negative. I am still bloating at night, nauseous, dizzy, and tend to get emotional easily. Since multiple run in my husbands family my mother-in-law said that it was possible that I lost one of the babies I was carrying. I'm scared that I'm no longer pregnant and am unsure of what to do. My friends have had similar experiences to where the pregnancy tests didn't pick up their hcg levels up to 4 months into the pregnancy. What should I do?
