Some advise please!

Hi ladies, I came off my pill to ttc my 1st baby on the 2nd of this month. I have had a 5 day period literally a few days after. Me and my husband have had sex about 6 times since. The last week I have had a headache that even paracetamol won't budge. Been extremely tired and grumpy. Most like side effect from coming of the pill. Anyway tonight I have had a teaspoon amount of discharge that was thick ish and not clear nor white. Why is my body doing this?? 💜
