Ladies I could really use some help /:

Took an OPK yesterday morning: negative but noticeable second line...

Last night I noticed a streak of pink in my CM before sex and some light cramps.

This morning around 9 am I took an OPK and it was negative but super super close! So excited! I saw a prism rainbow made by a mirror and window and got all excited thinking this was a sign.

Took a test around 3 pm (just now) and it's completely COMPLETELY negative.

I feel so deflated. Am I having an anovulatory cycle?

In the pic: the top is from this morning and the bottom is from just now (3pm)

Please help? Any advice?
