Why would I get multiple positive pregnancy tests then negative?

Can a pregnancy test be negative and then positive 2 days later?

If the result is negative, it may be a good idea to take another test in a few days, to give hCG levels a chance to rise. Very few medications, including fertility drugs, may cause false positives.

How fast do hCG levels rise?

In the first four weeks of a viable pregnancy, hCG levels will typically double about every two to three days. After six weeks, the levels will double about every 96 hours. So, if your baseline level is higher than 5 mIU/mL, your doctor may order a repeat test a couple days later to see if the number doubles.
