Help me please 😭

Madison β€’ TTC for 2years in November, praying each month for a BFP 🀞🏻

I am ovulating at the moment but I just went to the toilet and there is what looks like old blood or really brown discharged on my underwear...

Also a drop of blood may of fallen into the toilet whilst I was on it, not 100% sure cause I was crying 😭

Anyone know what's going on!? I also have little cramps 😞 help please!
