Need advice - Spotting after bfp...taken several tests

Ju

So five days before AF was due i began spotting very lightly pinkish for 6-8 hours. I knew I could potentially be pregnant so I took my first frer hpt and got a very faint bfp but a line none the less. I have been making myself crazy taking a test every morning (4th day in a row) and the lines have all been light if there at all within 3-5 minutes. This morning I took a digi and got a bfn...after work took a frer and got a more solid bfp. So not only am I confused, but I started spotting a very faint pinkish/beige again! It was almost nothing on the tissue and I know the only sure way to know is to go to the doctor, but I'm not even sure if I should make an appointment or even tell DH the news
