1st month ttc after finishing my contraceptive pill, glow said I was due af on the 19th, if still using my pill I would be due today 21st.
Did a test (clear blue) supposed to be able to detect up to 4 days before af on Saturday 17th and it was a bfn
No af yet but I have watery cm.
Cervix is soft and high.
Is this normal as its been so long since I had a normal period I'm not sure what to expect?
How long did it take for you to regulate after coming off the pill or did you conceive straight away? X
