I’m literally about to give up... πŸ˜“πŸ˜“πŸ˜“

Last Thursday as y’all know I got a faint positive in the afternoon. Well Friday I tested and Saturday I did it was negative. Friday was in the afternoon and Saturday was in the AM. Those were cheapies. So I tested yesterday afternoon it was a 1$ cheapie and negative again. Well I caved and used one of my First Responses this afternoon that I had been saving and nothing but a indent line. I feel like I’m going crazy and have to much hope that something will show up. I’m about to quit testing..I’m only 11dpo I think. I’ve had symptoms like sore boobs, gas, extremely tired, hungry a lot, lower back pain. I just don’t know what to do anymore..πŸ€·πŸ½β€β™€οΈ advice please?!
