Day 41 and still BFN--what should I do?

Candi • Baby one born March 2016! Was TTC for 20 months. Baby 2 born 6/2019. TTC for 20 months. Now TTC baby #3. Scar on my tummy is from surgery I had as a baby.
Hi ladies I am 41 day late and have gotten 3 BFNs!! Should I call my doctor and make an appointment? We've been TTC for almost 7 months surely my period has regulated after being of BC for that long. Help!!
​I've had a weird chest pain/pressure for the past week as well.
