Pregnant but worried

jager

I tested one wk ago and had really decent strong pregnancy lines. I’ve tested in the last two days and there are lines there but are really quite faint in comparison. I tested yesterday in afternoon and this morning. Is this something I should get checked. I’m only 5 and a half wks. I’ve had 2 days of light spotting. Like 3 drops and a wee bit more the following day.
