Day before period

Steph

Hey everyone I am new to here and new to TTC. A bit of background information, I had my period on the 17th to the 21st of Feb. I think I have a 21/22 day cycle. I was wondering if anyone could help me with this. I was wondering if testing a day before period is due is too early? I have taken a couple of tests one came back with a faint positive and the other came back negative. The positive one was a cheapie and the negative was a first response. I feel like I am out this month. The symptoms I have been having since ovulation are sore breasts, a day of nausea, super burpy, different sensation in uterus, headaches and eye twitching? Has anyone had this happen to them and go onto have a bfp?? Haven't got any AF type symptoms yet so not sure if it will show.

Thanks in advance 🙂
