Hello there, just want some opinions. I’ve been with my partner for 5 years and have tried to get pregnant around 3 years now. No luck so far; but the past 2.5 weeks I’ve been really dizzy/ lightheaded. I had spotting which I thought was normal because I have had it before but usually after spotting my period comes. This time I had spotting but my period didn’t come. Also My legs feel a little tingling than normal and a couple of days ago my boobs started to feel a little tender to touch. I don’t want to think any of it because my period is due on the 14 of this month. Any opinions?
