I had unprotected sex 1dpo using withdrawal.
The thing is I had been monitoring my BBT and CM for two weeks. And the 3 apps I was using for this coincided that I wasn't fertile.
I still wasn't sure, cause I had what could have been called EWCM (it made me feel really wet for two days, but for the rest, I barely saw it stretch twice) during the days the apps told I wasn't fertile.
Also, my BBT had gone up from 36.4°C to 37.
So that day, I had unprotected sex five times. My CM was pretty normal, humid.
I knew that preseminal fluid could contain sperm, but I brushed it off because I thought I had ovulated.
Two days after, the apps' prediction changed. One said I ovulated on the 28, the other on the 29, and I had sex the 30.
Yesterday, 2dpo I saw very light yellow, creamy - transparent cervical mucus, once. And later I had this whiter, more consistent, CM that stretched around between my fingers. It wasn't like an EW, and it stretched. For the rest of the evening, it was cream like.
So, today, 3dpo my BBT dropped from 36.8 to 36.5.
Is it an implantation dip or a second estrogen surge?
I read I can't take a test yet, I would have to wait a week.
