Newbie

Hello! So my husband and I are newbies ttc and this is all new to me and idk what’s going on haha On the 17th I had very very light pink spotting when I went to the bathroom twice and wiped. Not sure if maybe I ovulated later than the app predicted or if this could of been implantation bleeding. On the 22nd I had the worse cramps all day long and my back hurt and I was extremely tired all of a sudden and had a headache. The headache continued the next day and then yesterday on the 24th I had a headache, lightheaded, nauseous, heavy chest, extreme fatigue/tiredness for like 3 hours and then it stopped. Like it was bad. And then Later that evening I had a gross metal taste in my mouth all night. Took a test the 22nd and 24th and negative. Could I be experiencing very early on pregnancy symptoms

or could these be symptoms of my period about to start? I was on birth control for 11 years and have had 3 normal periods off of it and never experienced any symptoms ever! Helppp pleaseeee 😬
