What the heck is going on?

My last period was march 19th. I had sex march 26th and 29th and april i had sex 8th, 12th and 29th. My cycles are irregular and they have ranged as far as 25 to 52 days. Normally it being in the 30s. We had sex using the pull out only. On april 21st i had light pink when i wiped and i have only done that once before that I remember and that was when i was later also. I have taken test. The first one either was vvvvfl or evap. The rest of been negative. The first i took was may 2nd. Then i took the rest march 3rd, 4th and 8th. My boobs aren't sore like normal, and not much acne like normal. I have been emotional more than normal and kinda nauseous when i am hungry.

The first test that shows either vvvvfl or evap

This last test was after the test had dried clearly and I know you arent suppose to reas them after that but normally my dried test doesn't show a line at all.
