Am I pregnant?!

Girls I need your help🥺

I’m desperately trying to fall pregnant with my second but have had months and months of negative results😭 this month I’ve had unprotectedsex throughout my predicted ovulation window. About 7 days after “ovulation” I had mild spotting and very mild cramps for two days. I never ever spot however my periods have been longer than usual lately. I took a test and it came back negative however sorry for the tmi my discharge has been so watery and I got that with my first. I’m extremely exhausted constantly and getting quite a few head aches and nausea over the last couple of days. I don’t know if because I’m so desperate I’m over thinking or I am pregnant. What do I do?😭
