Ok so back story. I always have had regular menstrual cycle even after coming off the pill with my last child I was pregnant right away the next cycle. I’ve been off the pill for 3 months now because it was making me sick. Anyways I’m now 5 days late for my period with no sign of it coming back(no usual pms symptoms). Last month and the month before I had a normal cycle. I’ve taken quite a few pregnancy tests the last few days and I’ve had negatives. Today I took one that is questionable but very very very faint if its there. What do you all think? Should I wait a few more days or schedule a doctors appointment? Have any of you had negative tests at 5 days late and then got a bfp a few days later? This is a new one for me..am I crazy and seeing things?
