Confused

Danielle • I`m a 38 year old mommy of 3 beautiful daughters 19, 15 ,3 and 1 sweet little boy who is 1.5. Married for 5 years and pregnant baby #5.
AF is due today and did not show up yet. Yesterday I noticed a very light pink milky discharge (sorry for TMI) when I wiped. Took a HPT with fmu this morning and at first I did not see a line but around the 7 min mark I thought I saw something. Tweaked but can't tell of its a Vvvfl or just and evap. Really hoping it's just to early and this is it!!
