Period 13 days late...

So....I’m 13 days late...I have done 3 pregnancy test which have all come back negative.

I came off my pill 2 months ago as me and my husband want to try for a baby.

I had a period in January...so thought my cycle was pretty much returning but then I seem to have missed this month?

I have had strange symptoms like sore boobs, cramping on one side and lower back pain but nothing has arrived!!

Any idea how long it took to you ladies to get pregnant after stopping the pill? Also I’m thinking if I do end up being lucky enough to get pregnant but have missed my period this month would I class January as my last period??? Would the dates be a miss due to missing?

Sorry for the questions - I really want this to happen!!
