Anyone had a chemical pregnancy and had to take multiple blood tests?

I tested positive on a pregnancy test after what I thought was my period.. went to see the gynae but she couldn’t find any pregnancy sac. Took 2 blood tests last thurs and sat with hcg at 110 and 103.. now have to go back again tomorrow for another blood test.... and potentially another scan to make sure it’s not ectopic ( though gynae couldn’t find any sac anywhere last thurs )...
