Do i take a test or wait?

First time posting in here. I'm 28,married for 2.5yrs and TTC our first. Came off the pill in Feb and periods have been all over the place since. I'm now 4 days late to when i think i should have come on. Really sore breasts with bigger nipples, which is unusual for me, but been getting cramping for last few days, again unusual for me, with no spotting or anything. Do you think it's worth taking a test? Or should i wait a bit longer and try not to get my hopes up too much?
