I need some help...

So here is the deal, I ovulated January 4th. I was suppose to start January 17th. I am 8 days late. I got a faint positive about 4 days ago. But haven’t gotten a BFP yet. I have been tired, my boobs have been sore, I have been extremely bloated and constipated and have had head aches here and there and have been nauseous here and there. I stopped birth control in August and had a normal period in September then I didn’t have a period at all in October and but then had a normal period in November and January. Is there a still chance that I will have a BFP or should I just give up for this month????
