Am I having implantation bleeding?

Shelli

Help? I have never had this and I am 37 so I’m thinking it could possibly be implantation bleeding?

According to this app and fertility friend my period was scheduled to start yesterday and I should take a pregnancy test. Well the test was negative and the next bathroom trip I thought I had started my period. So I used a regular sized tampon as I would on a not at home first period day. When I got home there was almost nothing on it. So as usual used a pad at home and it was clean overnight which never happens on the first day. Then all day today it has just been discharge. Nothing to even penetrate a pad. Normally the second day is my heaviest day.

My other symptoms are slight cramping, achy boobs and my emotions are all over the place.

Thoughts? Should I message my doctor?
