I need suggestions please

Nicole

So I am five days late, the first day I wiped and saw a very small barley could see amount of blood so I thought it was AF but it never came. On my third day with no sign of AF I went to the bathroom and wiped and got a brown discharge I’ve never seen before so I looked it up and it looked more like implantation bleeding then old period blood. I went to the bathroom again expecting AF but nothing and no more discharge or anything but that one time... I’m five days now and I’ve been nauseous to certain weird random smells and I’ve been only having cramps in the morning and the rest of the day is fine which isn’t usually normal with my periods. I have been ttc for a little over a year now so I’ve had many negatives so I’m scared to get my hopes up. So any suggestions??
