Ttc is so hard 😭

DT 🎀
Advice?!? 💗  So me and my partner have been trying for a baby for a while after a horrible ectopic pregnancy in December,  still no luck as of yet, but started getting really sore breasts over the past few days and I'm more tired than usual. 
I am due my period in 4 days, is it to early to test?
