Need advice

El

I been trying to get pregnant for 3 months now since I got my iud removal and I have miss my period for 3 days now an I’m not sure if I’m pregnant cause doctor said it takes up to 3 to 6 months to get pregnant probably a year after iud…. I need advice on what I should do? My sister in law says it can be menopause which I told her it’s rare to get that in my 20… please get back with me!
