Jan 8-12 I had my normal period then had sex on the 13,14,16,17,20, & 21. According to the "My Days" app I was fertile the 17th-21st then ovulated the 22nd.. 5 days later on the 27th I began having some light bleeding that lasted for about 2-3 days followed by 2 more days of seeing pink but only when I wiped so no panty liner or anything else was needed. Once that was over I waited a few days then had sex again Feb 3,4, & 6th.. My expected period was supposed to show up Feb 4th but that did not happen so I went back to the My Days app and marked the light bleeding I had from the 27-31st and upon doing so, my fertile window showed Feb 1-4 and ovulation on the 5th which definitely throws up the red flags! 12 days later I began to have the pink spotting only when I wipe, followed by 2 days of reddish brownish discharge, followed then by 3 days of what appeared to be cervical mucus, then some more light spotting to top it off but not needing a panty liner since it was only there when I wiped... I took a 88 cent HPT while the spotting was only apparent when i wiped but the test was negative... I have so many signs from increased eating, frequent  uriniation, tiredness, bloated, weight gain, always wanting ice cream, breast may have gotten bigger but idk maybe its just me.. it's crazy but no vomiting or sore breast (sore nipples tho) so I kinda rule out the possibility... Can anyone help at all? I want a baby so bad but I don't want to over think it..
