TTC baby no 3

Fozia

Hello ladies, hope you are well. Just wanted some advice. I had my last contraceptive injection in October which would have lasted until January. Had irregular bleeding Jan and Feb. In March I bleed lightly for 1 week and had what I thought was a period the following week. Followed glow app for predicted ovulation but am now 17 days late but all tests are BFN. Any advice ladies???
