New to this! Long post.

I am new to this app and need some help. Please no rude comments. We have been trying for 6 months now and this month has been different. My periods are very irregular so it’s hard to tell when I’m actually late. I have been very nauseous the past two days and vomited on the first day. I also felt like my period was going to start but never did, just cervical mucous. After having intercourse last night I am now bleeding only when I wipe and it’s either pink or light red. Is it AF showing up late

again or just spotting?? Any advice needed!
