Please help. Opinions needed...

Hi ladies,
I think it's too early to test but I'm looking for opinions...
So, from September to 27th February I was on the mini pill. It mucked up my cycle and caused it to go all over the place with no pattern at all.
On 28th February I started taking Microgynon because they stopped making the mini pill I was on.
I made love with my partner without barrier methods on 4th, 5th and 11th of March.
Yesterday and today (15th and 16th of March) I have had very light bleeding which has been brown not red.
Could this be implantation bleeding? When can I test?
I simply can't work out the dates!
Thank you in advance!

Its could just be a breakthrough bleed as your body is adjusting to a change in pill - I once had a breakthrough bleed while taking the pill without a break to try and prevent having a period but I ended up with a brown bleed for about 2 weeks because of it. If you have been taking the pill its difficult to know when to test if you suspect you could be pregnant. I'd go with 4 weeks after the last time you had a break from taking the pill.

I used to bleed every month mid month on microgynon

That's helpful to know. Thank you ladies.
