Advice please (potentially TMI)

Jennifer
You all seem very informed about TTC etc.. So was wondering if somebody could help. Had chemo four years ago but was pregnant six months after it finished and had a healthy baby boy who is now two and a half. Had a mc in March of this year and a d&c. Since the d&c my periods have been regular (although they haven't been for my whole life prior to that). According to glow (only been on it a week) Af was due on 9th July and so far ... Nothing. I have had pregnancy symptoms - metallic taste, fatigue, hot flushes, nausea, back pain ... although boobs are not sore (they were during last two pregnancies). Have done tests but get bfn ... What should I do?? 😏 Confused! Frustrated! I am 39 - could I be going through the menopause? Sometimes get hot feeling in my pelvic area and think it could be Af symptoms but then ... nothing happens. CM is white and milky (sorry if TMI).
