I need some advice it's been 43 days since my last cycle. I had one day of spotting thinking it was implanting bleeding I have taken many home test and all have come up negative. I also have done a blood test at the doctors and it has come up negative. I'm debating if I could still be pregnant or just stop trying and get on birth control. And if I do get on birth control should I just set up an appointment right away or wait till I have a period?
