In Shock! BFP?

Have been really down lately. Found out a month ago I had a thyroid issue and thought for sure it would be a rough time getting pregnant. Didn't get my period and though I was having an irregular cycle. Got EWCM at CD 35 (11/27) and thought, "this is weird, oh well let's BD anyway!". Randomly took a test today using Wondo and got barely a line. Took this tonight and...still can't believe it! Hoping it gets darker....
