Good afternoon...

So for the last 1yr 1/2. I’ve been trying to get pregnant 😩 nothing has happened so I said it might be my weight? So I started working out. and yesterday I did work on my stomach... and well today I went to use the rest room and I had very LIGHT light blood.. and I haven’t had my period for 4 months now 😪.. took a pregnancy test the first month and was negative.... so any help or tips?
