Still confused..

Been trying to conceive for a month or so. Had a 1 day period on feb. 12, which is weird for me. My Ovulation day was on the 26 of Feb, and had intercourse on Feb. 25. I noticed brown spotting on 6 dpo and a red spotting on 13 dpo in the morning and a brownish clear discharge at night. My period was supposed to show up on 14 dpo but it came on 15 dpo which was March 13th. It lasts for only 4 days. The flow was very light to moderate and was dark brown, which is so weird for me when in my period. I had intercourse in 6 dpo and 13 dpo too. Also on 14 dpo. I felt super diferent after intercourse, like some days after it. I had felt weird symptoms that never had happened to me before my period and in my whole life. Like, nausea, dizziness and bad taste from some foods that I love. Today I'm on cycle day 10, and still think that there might be something wrong or diferent with me. Anyways, I tested every week after intercourse and they were all Negs. We'll still be trying and hope to get a BFP.

6 dpo brown spotting
