Ttc for on/off for 10yrs with endometriosis. Was on Sprintec for a break and reduce endometriosis symptoms and my lmp started 1/21 and I did not take my pill that day as we wanted to start trying again. Around 2/9 my breasts were so sore and stayed sore (now feel full/heavy but not as sore). I had pink tinged mucous once on 2/13 and once on 2/14. My period always varied usually 28-31 days-not late. I’ve had intermittent mild cramping on different days/times. All hpts have been negative, including this am. Have never been this late-should I keep testing and wait a bit longer (how long?), or call OB?
