Looking for advice

Hi all! I had EWCM on 25th January, I had intercourse. 18th, 22nd, 24th & 25th. so is 13DPO long enough to take a test, I’m feeling very nauseated. Strangely had a nose bleed (I know may not be related but I’ve only ever once had one when I was a child) and boobs are very sore and tender to touch, sorry if I sound stupid only the last 5/6 months I’ve been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> after having a M/C in June. Any help would be deeply appreciated ❤️
