MN TTC gurus please help I’m so confused. I’m currently on CD36, apparently 9 days late. Though for the first 10(ish) days of my cycle I was taking the mini pill - though I was only on it for 3 weeks in total because my MH tanked. I thought I felt ovulation symptoms (mainly increased sex drive) around days 12-14 which would be very normal for me. In the week after that DH and I did have sex and weren’t too careful, though can’t remember when exactly.
When my period was 3 days late last Sunday I did a test, BFN. Still no period this week so did another IC this morning, initially BFN but a line had appeared when I went to throw it away. I immediately did another and a faint line appeared in the time (picture attached). Couldn’t find an FRER anywhere, but did a knock-off pink dye test (negative, but looked like an ink run so not sure it’s valid) and a CBD with weeks this afternoon and it said not pregnant. If it’s roughly 2 weeks since we last had sex surely it’d be clearer by now? Does this mean it’s a chemical?
