Boyfriend and i have been trying for a year now. After i had 7 year IUD...

Finally according to <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> im now 5 days late. I took a test yesterday it was negative. I have been light red spotting some brown too the past 2 days. We had sex today and since then im heavier bleeding. Still bright red but not spotting .im dead tired all the time, nauseous, we want a baby so bad and I'm almost 35 please help me...is this normal for early pregnancy? Should i test again or is it over for us?
