help anyone please.

Kirsty • Hi I am 30 pregnant with our first baby. 😍
Hi everyone, I'm just after a little bit of advice. (Sorry for the long post) 
I came off the pill on the 1st of march and had my 'withdrawal bleed'.
Me and my Husband BD every other day whilst glow told me I was possibly ovulating. 
I've had extremely sore nipples, indigestion, and sensitive to smells. I was due AF on the 28th and still no show. I did a PT on the 29th and got a BFN
Is there anybody out there who can please tell me if they had a similar kind of thing after coming off the pill, and how long it took to fall after coming off the pill.
I know this is only our first cycle trying but I guess I just need some reassurance. 🙈
