Fainter BFP on second test.

My husband and I have just started trying to conceive. I took a pregnancy test 11 DPO during the afternoon and the line was a medium level of darkness. The last day or so I’ve been feeling different and am so worried about a miscarriage. I took a test this morning, 14 DPO and with morning urine and the line is not any darker, if anything it seems fainter. Has anyone had this happen to them and if so, did you miscarry or end up with a healthy pregnancy. Thanks for reading. Sending lots of baby dust to everyone!
