Period maths...

So suggestions would be greatly received please ladies... I know I can’t pin point when I ovulated precisely because I don’t opk or temp, this is only our first couple of months ttc and trying to take a relaxed approach for the time being

So I took my last bc pill on 14th dec, I had a withdrawal bleed 18-21st dec

My first natural period came on the 19th December giving a 32 day cycle for that month, just going on the assumption of a 29 day cycle whilst I figure it out more my ‘fertile week’ was 29th Jan - 4th feb,

You can see when we BD in that time, 29 cycle suggest I should have got AF today/ tomorrow, but I’ve had so much bloating, cramping and nausea that doesn’t fit with my normal pms symptoms, I’ve had nothing but BFN last tested this morning, if I ovulated late with a 32 day cycle we didn’t next BD after assumed fertile window till the 8th, could I still be within a chance? Today my boobs seem to have taken a mind of their own and are defiantly bigger and fuller (this never happens) but I do remember is being something I noticed with my pregnancy with my last baby 5 years ago, sorry if this is super confusing 🤪
